I don't have a problem with the WCAG definition of a path-based gesture. A swipe gesture does not just rely on the two end points. Although the gesture does not have to go through any specific points, it must not do certain things, otherwise it will not be recognised. For instance, if you traced a wiggly line from left to right it may not be recognised as a swipe even if it has the exact same end points are a straight swipe.

Also, devices don't respond to correct gestures if they are made too slowly, or sometimes if they are made too fast. For instance, when using Voiceover on iOS, I always have difficulty with actions that require swiping up from the bottom of the screen at specific speeds.
