You'd need some definitions to clarify.
Using my interpretations:
Test effect I believe you are using as what I'd call the test outcome,
which can be pass or fail.

Post condition is some aspect of the UUT, usually state, that may impact
other tests, hence needs to be recorded. A clearer definition is some state
different from the neutral state in which the UUT commenced testing.

Which I hope my definitions clarify. Yes, this contradiction helps
clarify that.

In which case define them and justify their removal.
