high temp is the point, though. We're inducing a "fever" to help the snake fight infection - the cool side stays cool, and if the snake stays on the cool side constantly when it's normally going back and forth, temps can probably go back to normal.
Fevers kill bacteria, and by providing extra high temps on the hot side, you provide the snake the opportunity to give itself a "fever". I'm not entirely sure its the same sort of fever in reptiles since their body temperatures fluctuate so much, but higher temps fight off infection. They do NOT stay that high for more than a week or so though.
Make more sense? You can always call up a vet and get a professional opinion
they can't charge you for a phone call.
