Having owned a dive shop with two schools attached too it and been a commercial diver I think I can probably make a guess at the right answer.
Unless you're deformed you should float with shoulder and legs on the surface. If you shift or try to turn over the air can go to your arse so you can float face down. You will panic quick enough to lift your head and float upright.
The easiest thing to do as suggest is squat with your fingers in your neck seal. You don't want excess air in the suit if your wearing a life jacket
When you're diving air shift to legs can be a problem in the not so well trained and I've seen uncontrolled accents from depth and it ain't pretty.
Just get the air out to be on the safe side
