Could be interpreted that way. Could also be interpreted in the way I explained...

(see what I did there...)

I don't see anything from that thread or comment implying, let along stating, that the alleged Brennan on the old clip is a deep fake. Wouldn't it just make more sense to be pointing out that Brennan was indeed at the event to demonstrate his prior Communist ties (whether or not they were bonified)?

Yes, certainly possibly that the lie was used to entice bonified communists into revealing themselves, e.g. a honeypot.
