Okay... is this weird?

My juvi bp is very regular about eating, and well, the rest. Usually about 2 days after eating, he pees, and a day later comes #2. But the weird thing is, it's really easy to tell when he's done it...because he always poops/pees in his hide and then when he's done, refuses to go back in the hide!

He actually seems to actively avoid the soiled area. If I remove the dirty bedding or clean the waste off the hide and set it back in the tank, he'll go right inside. I know to look for poop if I see him outside the hide before it's close to his next mealtime...

Today I caught him wrapped around the outside of his hide with just his head inside as if he was trying to hide without being in there. Curious, I picked up the hide and sure enough, a very fresh stinky mess.

I didn't know snakes were that caring of their toilet habits. Anyone else seen this? Or is my snake just a prima donna?
