Did you read 11.6?

I think all this says is that if an assignment statement raises an
exception (due to a language-defined check), then in the exception
handler and further on in the code, you can't count on the value of
the target object being normal.  You can't count on it being abnormal,
either.  But if no exception is raised, then this doesn't apply.
