They wouldn't have mentioned it at all if he wasn't with the company - it says RECENT, meaning he RECENTLY has endorsed it, not that he isn't endorsing any more.
I think for everyone so freaked out about this, just move on. I've noticed a dozen places in last week's PRs where they could have said "JUSTIN BIEBER!" and just said "celebrity endorsement." Maybe in the long run they don't want to be known only as the Justin Bieber company! Maybe their one and only goal is not to reassure you. If he's not in and not in big, we all know where we're going near term, so just place your bet and move on.
