He's recommending against NFBs after we open and an overcall. e.g.....
1D (1S) 2C should be forcing
He isn't talking about auctions after opponents open. E.g...
1D (1S) P (2C)
I'm guessing his reason for liking NFBs after a strong club is that we have a lot of interest being in the auction but need to start finding fits before we get preempted out of them.. In any case, he has the ability to show suits in forcing and nf ways against low level interference.
New suit on the 2-level after overcall What is standard near you?

In my experience, negative free bids work really well when opener has a weak notrump and not so well otherwise.
In a strong club system with moderately strong notrump (i.e. what Meckwell play), the 1♦ opening is extremely often a weak notrump. This frequency is much higher than for either 1m bid in a standard system, because you exclude the strong hands (16+ would open 1♣) and because you include all weak notrumps regardless of minor suit distribution. Perhaps in a standard-ish system where 1♦ is unbalanced and all weak notrumps open 1♣ you get close enough to the same frequency to make NFB worthwhile. Also if you play Polish club, you almost have to play negative free bids after 1♣-(interference), which again works out okay because 1♣ is so often a weak notrump.
Personally I prefer transfer free bids opposite these kinds of openings, for much the same reason (I think transfer free bids are slightly better than NFB in general).

I played both FORCING and NF but Constructive with different partners. The best solution imo is to play transfer responses to partner's overcall. it gives much more flexibility to both overcaller and responder.
This also works when we open and they overcall. I see more and more top players in BBO vugraph playing it.

I play them as forcing and I don't know anyone who doesn't. I'm not stating that to imply that 'no-one plays them non-forcing'...only as a statement that in my relatively limited world, the forcing meaning seems universal.
Indeed it does mostly seem a statement about the limited nature of your world - non-forcing is Bridge World Standard.

NF
Our structure is a tweak from Ambra and is sort of extended Rubens advances. So we have transfers starting from 2♠ here and lower bids are NF. Transfers to a new suit show invitational+ 6 card suit. (about 13+ points)
Free bids thus show about 10-15 and five card suit or 8-12 6 card suit.
GF hands with 5 card suit are a bit problematic but there are always ways around them.
We have this same transfers theme going through whole system in various places and it's pretty nice.
