I'm not sure what a confident creep would be like. Confidence is confidence. A confident man knows restraint, and as long as he's good with restraint, he's not in danger of being a creep.

It is good to play with expectations, to acknowledge them without actually "acknowledging" them. A creep wouldn't have the confidence to let this play out; they have to confirm that the other person is aware of the "acknowledgment" being played out. It's like some guy saying "did you get it? Did you get the joke?" Except the creep is saying this with everything he does. His body language, tone, talking speed, and even with his language.

A "confident creep" is a contradiction.
