Another related effect can be used to actually derive contradictions
in Mathematica. Try this

It returns 0. The assumption was that Im[x]>0 so here Mathematica
clearly contradicts the assumption.

Obviously this suggests one should be very careful when using
inequalities with complex quantities. I think this sort of bugs should
really be fixed considering how much trouble Mathematica usually goes
into to ensure that real quantities are not assumed in expressions.
