Unfortunately, this writeup doesn't mention any words like "spin" or "rotation" or "angular", not even to disclaim that those aspects are not presently being addressed. It looks like a great resource for kids in grade 11 or 12 physics.

Yes. They can bounce back and forth due to the spin reversing. I believe each time they make contact with the floor, high friction causes of spent to stop, while they undergo a rotational deformation, which then reverses direction.

The intended audience is the author himself.

Chances are the author is in 11th or 12th grade. And you two might be on the same page.
(Just joking).
Since it also doesn't mention friction I'm a bit confused what effect, if any, you were expecting to see.
Dealing with friction complicates matters significantly. At the very least you can't expect the collision to be elastic.
Actually, I believe that it can be elastic, if the friction is so great that the surfaces do not slip the entire time they are in contact.
