No worries. It is rather the date that you compare it to that changed (filing rather than invention). I could have expressed that more clearly. It actually does change the dates for when patent documents are considered prior art (as described in the first paragraph I referenced), so it is easy to get the issues confused. The effects of first to file on how prior art works are, in my opinion, way more important than the litigation edge condition it eliminated.
