Quite, but if you backtrack to my initial statement, it was

set it to null via external means, such as memcpy, move, etc).
It's only true as long as you have full control of the source.
Once you're using libraries and generic code, it's possible
that it's out of your hands:
It's always true, because I explicitly wrote *might*, not *will*,
to indicate that it depends on your use case. Your example is a
common use case where you can't skip the check.
