I don't think it's anything to be worried about as long as he's not walking or keeping it permanently like that. My beardie rests his hands awkwardly at times while he's basking or if I position him strangely. He actually won't fix it himself, so I have to fix it myself because I think it looks uncomfortable. Right now he's basking with one of his hands with his front toes pointed toward his tail and the other hand resting on the brick. I honestly think that's how he arrived at the brick, plopped himself down, and was just too lazy/didn't care enough to move it.
