I had a chance to dig into this some today, and I think that just this situation can be safely disabled.

The Axis or "on" snaps are not really useful in this kind of situation where the command is working on a particular plane and that "on" or "axis" snap point is off the plane and getting projected back on to it.

So I've got that particular thing disabled for the next v2 beta.

It is still possible for you to get some similar jumping around though if you hit a variety of other snaps like "end", "mid", etc... - but projecting those ones are potentially useful so I don't want to do an automatic disable of those (you can do a quick disable of those too if you want by holding Alt same as now).

But the axis snap can tend to affect a pretty large area of the screen, so it should help things work better to not have them kicking in for these situations.

Thanks for posting about the problem and for making the video, that helped a lot in making this improvement, it was definitely a useful contribution!
