I don't know either, never used the tool. Maybe @Campbell Barton (campbellbarton) can quickly check if the tool behaves as expected.

However it would still be useful if you could come up with one specific case where the tool is unpredictable.

This is working as intended, in that there are rules for ripping that aren't broken/buggy.

Although the cases you've found are situations where the logic isn't as obvious.

When there is a partial rip along the corner, the method used will try to rip off two faces.
This is because ripping away edge loops is more common then ripping individual face corners.
