This is exactly what I heard him say..IIRC...go short gamma as the VIX was so high and he also pointed to the fact that volume in the puts far exceeded volume in calls (ATM and NTM) pointing to perhaps panic covering/protection
I also should have made it clear that this position will not stay neutral. The closer to September expiration, the greater the long volatility exposure. The idea is that you are going to roll before that happens...
