Multipoint and Path-based gestures - Websites in desktop

Hi Everyone,

Going through WCAG 2.1 SC 2.5.1 which talks about providing single point
alternatives for multipoint and path-based gestures leaves with some doubts.

The sc talks about mouse pointer as well among all other techniques making
it look applicable on web pages in desktop/laptop as well. However, I
cannot relate it to an example which I can encounter on any website.

I was going through one of the interpretations of the success criteria,
there in the example the author indicated swipe up as a path-based gesture.

Some websites like Google Maps web view exercise zoom in/out based on mouse
wheel motion forward or backward. Can this be regarded as a path-based
gesture as well.

Need your inputs in understanding the topic.

Thanks,
Vaibhav
