You're correct. Bivi retweeted that same person twice and made mention of how they expanded into seven states and keep expanding everyday! I'll take that update whether the tweet was originally created by Bivi or their 're-tweeting other people's tweets.'
I think Chazz mentioning Bivi is a good thing; it's not a national plug, but it sure does help that he's mentioning the brand and giving it exposure. It's also going for $13.95 on his menu at his restaurant, and I wouldn't have known that or even looked into it without that tweet when I first began researching doing the DD on this company.
