Warning, another long post, lol. Long because I'm attempting to describe stuff.
Interestingly I've done something similar but not cause of BPD/lack of self, more because of having NPD parent/s, and lack of ability to share self with others. (my comments might be useful/valid because NPD parenting often/usually is said to cause BPD, so even if its different, there might be some insight in it somewhere to what causes mirroring.)
I had to learn to act "how I was supposed to" to keep people off my back, so while I've always known I'm me, and have always had a sense of identity even when that sense has been just "everything and nothing", I've had no [external] identity to interact with others through, or at least not been used to interacting as myself because I'd have to keep it reserved for when I could.
So I learned being myself wasn't acceptable, so I'd resort normally to mirroring other people's behaviour, because people like people like themselves and it got guaranteed good/easygoing results most of the time, and I'd mirror people even for very short periods of time (even 2 minute conversations) - I didn't have to admire them in any way to do it. (more likely I learned it because my parents gave me less hassle if I mirrored them - learned it placates most people.)
So because of my limited opportunities to develop my own [real] personality as a child, later on I took bits and pieces from here and there, friends, aquaintences, movie characters for a while playing around with them, getting used to what it was like to interact with the rest of the world in different ways - in some ways trying to free myself up to be able to "just be me" with other people when I wanted to - and to give me a chance to try to develop an [interactive] personality I like, instead of hating the way I came across because it was something I'd learned to shut other people up.
I have been able to be myself at some times, but the more you do it the harder it is to drop it, and it became so automatic it was hard to "switch off". (Sometimes integrated stuff in the sort of "false self" way that usually happens in narcissism - learned I can become who I want to get what I want or survive different situations.) [this may seem muddled and makes little sense] - yes stuff did get incorporated into my personality over time, if i liked it, but never the stuff I did for those reasons, more stuff I picked up from friends & aquaintences, then later adapted for myself and integrated e.g. stuff like sense of humour or way of saying something, etc. In the short term, yes, all sorts, but I'd always drop it and come back to myself[or what there is of me] when I'd finished being whatever I needed to be.
In essence, as a way of building some kind of identity (or maybe a shield?), in the abscence of one's own?
A bit like an actor playing a role? Or perhaps, even 'chameleon' like, in which one can shift personas or personalities (in a controlled way...quite unlike schizophrenia for example), and almost portray different personas depending on the occasion or social context?
Yes, a shield against people trying to control who I was. Not in the absence of me, and yes an ability to shift or an actor playing a role, but as a shield, and something going on between me and the external world, a barrier, a way to keep control both over what happened in it, and of my own personal space.
I try to describe it, there's truth in it but I sense possibility of dishonesty in what I'm saying, possibly the [emotionally true] answer is just "because if they want to try to make me who they want me to be, I'll just lie to them cause they're ######6 stupid, and now they can't control me." I have always hated people for making or expecting me to do it.
My thoughts in relation to BPD are if a child is actually attached (including insecurely) to a parent who expects them to "be them", there is the message "if you love me you have to be me." I guess my example is what happens when the child isn't.

What is meant by the term 'lack of identity?'
Would the above serve as a suitable definition?
I thank you
Aw ok, maybe my post is useless then
My answer would be depends why you do it, does it include a feeling of lack of identity? and also "I don't know". lol
