Hmmm...it does look like they are twisted. I'm stumped, just like you are. Of course, I still don't quite understand all of the mechanics that go into stitch composition.
I think this calls for the knitting gurus. I'm sure someone will be able to help you better than me.
Sorry!! Good luck! I'll be interested to read what the experts suggest.
Since you take great pictures, take a couple of pictures with you in the process of knitting. Maybe then we can determine exactly HOW the stitches are getting this way.
