I may be wrong in this thinking but it would make sense to me to have probe in the spot where you are trying to control the temp.
Doing it your way is how thermal burns occur. You NEVER want the t-stat probe inside for UTH as the snake can move it, Pee on it which will casue a massive spike in heat and burn the snake.

You want the probe on the uth directly OUTSIDE so you know the actual temp of the heating pad.
