I guess it could be additional overstitching to give the seams more strength. I gather there have been a couple of finds from the 14th century (some hose) where the seams are overstitched though it's the exception rather than the norm, and I don't think they used that kind of cross-stitching. But in an alternate reality, anything goes.

It doesn't really spoil the picture, aesthetically. It just niggled me a little!
