That's my source on it being a future soak test.
I wouldn't make that leap. DL says 'testers' and never mentions a soak. We saw 2 leaks on the first update that never made it to soak, and one on the last update (901). Certainly no harm in trying this leak, getting back to 902 is very easy now. And not giving you a hard time, just keeping it straight for all the folks that quickly read a thread and make a decision they may not like.
