GPs tweet is from a few days ago, the one you linked is from June and was speculation about what Google will do.

If your business depends on the idea that Big Tech can not track you, you need to do whatever it takes to keep it a reality. The cost of supporting a fork of Chromium might be too much when you are starting out, but when you are already a company of 100+ employees and 60M+ MAU, it becomes acceptable.
So, yes, if I had to guess with the information currently available, I'd say that Brave will keep away from v2 as long as it possible and as long ad the user base shows that this is what they want from their browser.
(Not sure where 'semantics' came from in the first place here.)
