Yeah I found it an interesting choice that they decided this even though they had just made it stricter by telling people to wear masks while seated at a restaurant. Maybe they made that rule stricter in restaurants so they felt more comfortable allowing guests to take their mask off for pictures? I dunno.
I have seen many reports that nothing actually changed for dining though, they still are told to take off once seated. Only a few that said to keep on till drinks then off. Still seems like it was a wording thing to align with CA.
