The rule probably should have said either SIC or PIC time. Since the date has now come and gone, the spirit of the rule is probably that they want you to have 1000 hours of experience as an SIC in a 121 operation before upgrading to Captain if you have no other 121 flight time.

Further, technically speaking, one could argue that if the pilot had the day off on July 31st, 2013 that he is not excepted from the 1,000 hour air carrier operations experience requirement because he did not serve as PIC on that date.
