That was my thought as you did gybe right after the spin pole was released (before actual take-down). You then DID have stbd while the Merit was holding their boom still on port tack. I guess I'm not clear when you were in the zone. It didn't seem to me that you were within 3 boat lengths until just a bit later, when it was clear that the Merit had to move over.
I guess it all came together right at the time when you entered the "zone" so it really doesn't matter. It really just looks like the Merit was trying to bait you into making a wrong move and they were forced to flinch at the end.
