Well, it's more that we've been asking clarifications about that statement since the EA started and we never really got one.
So yeah, a lot of people are defaulting to DOS 2 as reference since it matches to T what they are describing here.
Larian Confirmed it in Community Update #7. It's what mrfuju3 quoted.
I appreciate the callout, but for the record Community Update #7 was posted before the launch of EA and we haven't heard anything since from Larian about party locking since then. So it's also as @Tuco said; we're working off of a single paragraph posted prior to EA 10 months ago + our knowledge of how DOS2 worked.
