In response to Webaim's comment https://github.com/w3c/wcag21/issues/264 I have tried to address the difference between the requirements in SC 2.5.3 Touch with Assistive Technology
and 2.5.4 Pointer Gestures.

In response to Microsoft's comment https://github.com/w3c/wcag21/issues/196 I have attempted a draft definition of pointer gesture:

Pointer Gesture: A pointer gesture interacts with a target on the screen by positioning a cursor or a pointer like the finger or a dedicated pen over the x/y coordinates of the target. The cursor is positioned over the target via a mouse, trackpad, joystick or by an eye-tracking or voice interface. On touch screens, the pointer (finger or pen) can directly touch the target.
Simple pointer gestures activate the target below the pointer by clicking or pushing a dedicated button or issuing some other established form of activation (such as blinking or a voice command). Complex pointer gestures require a sequence of movements such as touching, dragging and dropping, or in multi-touch interfaces, target touches with two or more fingers, like split tap gestures or pinch gestures.

Please comment.

Have not yet addressed Microsoft's request to include exceptions for situations where complex gesturs are essential (piano app example) and for multi-user scenarios.
