So I’m logging the pointer down, pointer up, and pointer move events, and the id (via pointerInfo.event.pointerId)
this is a shot of the console logs to give an idea of what goes one when i first do a single press (line 1), then press again without releasing the first (line 3), then release the first (where the id changes, lines 4/5), then release the second second finger (end)):
im not sure what the yellow warning is but that happens on the second press
Basically the second press is only registered after the first press is released, so that final ‘pointer down - 201’) should really be happening on line 3.
hope thats clear 
… again hopefully this playground demonstrates the issue when opened in AR (ie the ball never turns green with multiple touches)
