tiling, underlayment, subfloor, screw length

Hello,

I'm installing some tiles.

I have a 5/8 plywood subfloor. I need to add 1/4 inch to one room to make it the same height as a connected entryway that is getting the same tile, which we want to be continuous.

I am using 3/4 #8 wood screws to lay down the 1/4 inch plywood. It feels like less than half get a good 'catch'

I feel like I read somewhere that any screws should not go through the subfloor (moisture/vapour coming up?) so I'm hesitant to increase the screw length but I'd love...
