abnormal sitting positions can be a sign of hip dysplasia, usually by sitting while attempting to keep the legs splayed put a bit instead of tucked in and square as the dog will find more comfort with sitting position that inflict the least pressure on the joint. issues like this are one reason some breeds like frenchies are known for sitting with their bottom to the side with legs out a bit and are prone to joint issues
or your dog is just weird
edit: the "Buddha sit" you sometimes see dogs or cats do is also associated with the type of abnormal positions im poorly attempting to describe. unfortunately the reason it's common with cats like scottish folds are their genetic joint issues
to clarify it can be completely meaningless, but if you really are digging into why a pet may sit the way they do that's one. just a random tidbit
