Thanks. That audio is the closest I’ve heard to a definitive source so far. Unfortunately, it’s still unclear.

If I’m expecting to hear a pause between “simpl” and “ex” when he says it, I can perceive a very slight one. But when I listen again expecting to hear the syllables “sim” and “plex”, I perceive that version just as clearly; maybe even more clearly.

His accent makes it difficult to work out his intent. (Note also the way he pronounces “adversary”: not at all how it’s pronounced in English, though not confusing in this case because there is no other word he could mean.)
