As long as the temps are right (not to hot in the warm end) Im sure its fine. Khan generally heads for the nearet hide after a feed and then sorts himself out when noone is about watching him.
Same as Rik here. Mine tend to go for the nearest hide then a little while later slither to the warm bit. To be on the safe side though check your temps are right.
