Do you think PUA Helps us create an Alter Ego?

My Question is have you guys notice most guys in PUA create an alter ego, sometimes even changing their names.

it works for them i see guys that are naturally more passive, become aggressive, flirtatious.

i was wondering if this was healthy, or is this the start of creating a double personality?

i feel like they are become more dissociated with who they really are? I've seen guy almost create a double life, and have trouble connecting themselves back to reality, so they become their alter ego to find comfort, is this healthy?
