User blog comment:LLight/Failsafe American Flag/@comment-1038387-20111107080858

For now, it's a goof. I noticed this same theory being asked to Greg (as of yet unanswered) so we'll have to wait to be sure. Maybe it's just overinterpretation.

The american flag is so crowded, you're bound to mess it up in animation. I have to watch it again to check, but on the left, there's 11 beams, and on the right, 13. We never really see the flag stretched out.
