I have the first printing of the PHB and the errata. It is written as I have written it.
The errata does not mention anything about a change in wording.
I just phone to a friend, who has the 3rd or 4th printing. The interupting of movement by OA isn't there anymore. It was not errata in anyway on the sage advice on Wizard's site... Which one is the correct way?
I think they removed it because it was causing the type of confusion in the rule that you are having. I can see and understand where you got it from after reading the rule. Perhaps many of us had enough background in 5e before it was released to know freedom of movement was a focus and that's why we never read that phrase as anything more than timing.
I have the first printing and it's in mine but I think it was just to help clarify the timing.
