It sounds like you are making a mid-corner adjustment. You realize you are getting direction too early and need to stop having your radius decrease or you'll be in the inside grass so you stand the bike up, so you stop turning so much then realize oh crap I need to tuck back in to hit the apex. I use my bars at turn in sure, but once leaned over, I use my brakes to make steering adjustments for the most part.
Once you turn in you shouldn't be standing the bike up after turn in for any other reason besides the drive out, unless you're getting stuffed on the inside, someone is crashing in front of you (special circumstances).
If you are saying that by getting of the bike more you can carry the same speed with less lean angle while holding the same radius, then yes that is correct. It's what you should be doing.
Lean angle = risk and you want to be a highest lean angle for the shortest amount of time.
