Theoretically maybe. Practically likely no. First of all, this is (assuming perfect sensor accuracy) fairly predictable in that identical interactions yield identical results. It's not very random. Then there is the whole point that the UI presented is context-aware in that it knows where your finger is. Thus is has the potential to be much better to use than a static UI. You can probably compare it to the clipboard copy button appearing near your selection instead of in a static place on the screen. While it's not in the same location every time, it's in a sensible and usable location. Of course, this all presumes that you never make mistakes, such as mistakenly assuming that a thumb from the left is used while it's actually the opposite. Then the experience is much worse. However, considering how often my phone thinks it should go to landscape mode while in portrait (never), I guess that's not going to happen often either. If things go wrong, it's your touch-screen. You probably wouldn't worry much about UI popping up in strange places when you simply cannot use your phone.
