That is the wording they have to use, right? They can't be certain that ALL the people who have seen these emails are caused by the buggy email notification code... I am sure some legitimate notifications were also sent out during the time, so how would they know if any of those were caused by something else?

It's not the wording they could use if they were sure that at least one alert was sent in error; then they wouldn't say it was likely, they'd say they know there were erroneous alerts. As it is, they're just speculating the alerts were wrong, which bodes very poorly.
