There was no real clarification beyond what it actually already indicates on both the DL and Velocity websites. (... Other than DL reminding their staff.)
The issue here is DL codeshares on AS metal - and that circumstance was not specifically referenced in VA's post.
In my opinion, no clarification is needed from Velocity re the AS codeshare - as posted by danoleary55 the first footnote on the Velocity lounge page specifically says it's not allowed:
Lounge Access with Velocity Membership | Velocity Frequent Flyer
DL's website, in my view, could do with some language input from Velocity - "Virgin Australia Club Members" is pretty meaningless and could give paid Lounge members aspirations of Sky Club access.
