> you make it sound like ... lowers the overall probability

I think that depends on whether you interpret the comment as trying to mitigate the perceived magnitude of the issue, or provide clear and concise information on what the issue entails.

I read it more as a "here's what the preconditions are, and there's some question as to whether the issue is actually a bug or not", and not "you have to do this for it to be a problem, so it's less bad than you think", so the wording didn't seem problematic at all to me.
