Yes, it's definitely official. Vocus stays in for the next quarter. Check the announcements for LYC (for example). They have published the official release from S&P.

Vocus is staying in the ASX100 list because it satisfies the criteria, not because somebody decided "hey, it would be nice to have Vocus in the index".
