Note how in the video you produced, moving cursor across the
right-most part of the line after C-e shows characters from the end of
the line. IOW, Emacs does know it is at EOL, it's just that the
window display somehow was not updated.

I think this is Darwin-specific display problem. 

Yes. I just tried on linux. It is ok on linux.
