Odd, I would think that if you have 2 segments then either one would
satisfy the topology requirement.

why is the plugin allowing 2 segments and then does not recognize there
is another one at  removal time ?

The plugin should not allow duplicates or reflexive segments in the
first place, so this should never be required then.
