The ambient temp is a side effect of the UTH's ... If you have the UTH's at the right temps the ambient air temp should not be too different. Ball pythons can bask and "suck" heat from a given heat source (that's a really loose explanation), but the air that they breathe into their lungs has to be at the appropriate temps as well. You couldn't put a ball python on a heat pad in siberia and expect it to survive.
The thing that you have to remember is that ball pythons need a thermal gradiant. One side 90-95 the other side 82-84. Setting a tank up this way allows the temps between those two sides to settle in anywhere between ~82-94 and gives your snake a wide array of temperature to choose from. The idea is that since your snake can't tell you what temp it needs at any given moment, you provide it with a range of temps and let the snake figure out where he/she wants to be.
