Using stills from the twitter video you posted, you can see the angle of that axis is going from fairly horizontal to much more vertical as the puck goes up.
The last photo here is still about 1 foot before the puck reaches it's top height and it's already very vertical.
These pics are just on the way up and well before any contact would have occurred and the angle of the rotational axis has changed dramatically on it's own.
By the time the puck gets to the top, it's going to be more or less vertical but it's still rotating around the same axis.
The axis itself is shifting and that has nothing to do with any contact.
You are mistaking this with a change in rotation axis which would have the puck rolling like a tire over itself and around the Y-axis.
The rotation of the puck around it's axis does not change at any point. Good Goal, E=NG.
