For anyone confused. I think there's a mistake in the codes at 7:11 in the adding while statements, the increments, decrements should be done before calling add. Also add statements should be called before remove ones for the reason you mention, here's why from the blog you link codeforces.com/blog/entry/46399?#comment-308528
I know this a year old comment, but it might help someone watching the video now. The adding statements should be done before the remove statements. It won't make a difference in the example given in the video, but see here for an explained example: codeforces.com/blog/entry/46399?#comment-308528
