Black Labrador crossing his paws

Question
Our black lab, about 4 years old, male, and neutered, has a habit of sometimes crossing his paws one on top of the other, kind of like folding your arms.  Is there any reason he or labs do this.  He is very well behaved and lovable, but we just wanted to know if this means anyting or why they do this.

Answer
Our one spayed female yellow Lab lays with her front paws crossed.  When she worked as a dog guide, her partner always commented on how lady like it was.  The only other dog I remember seeing do that is a Husky that also works as a dog guide.  As far as I know, it is just a individual habit.
