Yes.

> What are the cases when $_SESSION['imp']['user'] information is updated?

'user' itself is never changed after the initial login.

> What could cause eg. $_SESSION['imp']['user'] to get corrupted?

For everything but the password, only if your session store itself is  
corrupted or if there's a bug in PHP. For the password, you could lose  
it if the imp_key cookie were to be lost.
