Yes, but it would have been totally fair if they reused the same repo and maintained the old star count and everything, wouldn't it? They have maintained the brand after all.
My point is that it's difficult to define the limits of what people are endorsing. Some devs might endorse Angular 1 but not 2+, others might not care at all and just endorse Angular as a brand.
Of course there are situations where it's clear what is being endorsed, but not always.
