Why is this travel?

[potato]

It's hard to imagine someone is able to take 7 steps with the ball on his hand before doing a layup or dunk.

In this case if Jordan was quicker with his feet and wasn't palming, he would do 5 steps in a dribble motion, decides to pick up the ball immediately and does a step through which means he took 7 steps with the ball on his hand (5 while dribbling 2 while holding).

Is there a video that shows similar moves?
