I'm not aware of any statements he's made comparing it to arm-in chokes or anything, no. I've also found that certain techniques in Judo are outsizedly useful in BJJ - de ashi, hikkomi gaeshi, kouchi, yoko tomoe, etc. Basically the Kashiwazaki playbook. (Handily for me, that was who I emulated in Judo anyway.) However, there certainly have been people like Calasans who've used big throws like harai, osoto, seoi, o goshi (!!) to great effect in gi and no gi. Even Roger had some success with his judo applications. And we're also seeing some more dynamic players in the no gi scene use throws like uchi mata to access leg entanglements off the transition to the ground.
I think that if you were to train judo and emphasize things like transitions to newaza off of throws you were just using to knock them down (not on their back), minor ashiwaza like kouchi / de ashi, and sutemi waza, with judicious usage of throws like osoto, morote seoi nage, or tai otoshi mixed in, you'd have a great recipe for BJJ tachiwaza. The problem is that almost no judo places seem to play like that, other than apparently Pedro's.
