AFC haven't confirmed the draw procedure. 4 years ago, the 4 lowest seeded teams of the 10 qualified for the 4th round were placed in a single pot.
The publishing date has been brought forward by a week to 7 March so the last match day will be included in the rankings. Some might say the last match day would have been included even if the ranking would have been published on 14 March, but the draw takes places on 9 March.
If FIFA hadn't changed the publishing date, then the February FIFA ranking would had been the latest available FIFA ranking, as I wrote last Friday.
I did write on Friday to FIFA, AFC and all the involved FAs, but I can't claim the change of release date is because of me, although some people give me credit for this.
