okay seriously though that video explains it in a way that only makes it more confusing...
The reason the line and the circle have different number of rotations is because the circle path is travelling a further distance than the line. When you roll it along the line the CENTER travels the same distance, but when you roll it around the circle, the center is going a longer distance than the example with the line.
I hate when youtube videos do this... they present it in this mysterious confusing way, and you have to waste 15 minutes for the actual answer comes out... (I checked later in the video to see if they had this 1 sentence explanation, and they do but wrap it in 5 minutes of bullshit to confuse non-math types even more)
long story short... "No Diagonal Movement" --- lol ... lmao even
