Wasn't able to play your video, but the knife tool seems to work correctly here.

I can confirm that behavior here using given .blend file and also from default startup cube. Just close zoom-in, and as soon as the cursor goes outside of the edited mesh while drawing a cut stroke, things go wrong…

Problem here too, after using knife tool there are 19 vertices instead of 9 :( . Almost everytime Im using this tool I need to manually weld verts, merging by distance isnt helping here (increasing weld range is welding my other parts of the object)

@Gunzes : your issue seems to be the same as #62285 (Knife Tool produces bad geometry in certain cases (disconnected edges/vertices, overlapping faces)) -- not sure if this is realted to this one though...
