I have the ball python's enclosure in question outfitted with two identical hides, paper towels for the moment, and a 93*F hot side and 87*F ambient air. I am using vision cages, instead of utilizing either of the hides he instead lodges himself on the lip above the window. The only reason that this bothers me is that I do not visually see him making using of the UTH for digestion.

Should I be concerned or will he get the heat when he needs to regulate himself?
