Yea, those are separate issues, but it's hard to tell what you're referring to when you say jerkiness.. Regarding the fluidity (aka no stuttering or jumping between frames) I believe they've made great strides in this area. Looks much more natural in game. The replay you mention does seem to bring to light some of the after-the-whistle transitions that can certainly see some improving, but I disagree with your statement about the game not rendering properly. Unless things change from these videos, it's got to be one of the more fluid running/looking games out. Doesn't come close to Uncharted or anything but still impressive.
Edit: One reason for the lack of transition animations for after the whistle is probably because of their emphasis on post-whistle cutscenes. In gameplay, after the whistle in 10 (and now probably 11), you're often going to run right into a cutscene focusing on a few well animated players. Puts less emphasis on general transition animations for every player after plays.
