That still allows your snake to pick its temperature. Giving it hides in cool, medium, and warm areas will also help. When I added more hides I found my snake liked the cooler areas, before that she stayed towards the warm.
I kept track of the temps my snake stayed in and adjusted the warm side. When it was 85F on the warm side she did not stay there, only passed through when wandering. At 82-83F she uses the warm hide.
Observe your snake, it's interesting.
