This thread is full of LAWL, right from the beginning.
You provide NO solid evidence to back up your claim besides a thread to a wiki link. Which, if you've ever taken writing classes or have gone to school, isn't something you should be using to solely base your arguments of.
If you look at the picture I provide (something you should do to prove your point), you will see something that illustrates a lack of continuity with the manga.

If you read these panels in the correct order you will notice that before Minato "awakens" his SM, he throws something at Madara's foot. What is it? Well its one of his marked Kunais that he uses for his teleportation technique. Now, that isn't the mistake, but the fact that he enters SM while throwing something is. It is already stated by Pa and shown by Jiraya that one has to remain perfectly still to gather SM. However, just prior to entering SM, Minato throws something. Doesn't that go against what Kishi already stated? I would say it does.
And don't even bother saying its because he's a genius that he was able to do it. Because I am sure that if it were possible, Naruto himself would have figured it out as well.
See, I have given you proof why I believe its an ass-pull. Something you should do.
