I could see how you could interpret the statement as both of them not being combiners but with the listings, it’s clear that only one of them isn’t.
I don't see how. He said two commanders to disprove that theory, which implies that both commanders will be doing that. He didn't say two commanders, one of which will disprove that theory.
That said, I just realized he could be, and probably is, talking about a 2027 commander. Getting a splat of listings recently kinda biased me towards his answers being about 2025/2026. If Generations 2027 is the protectobots, and if they don't do Infernicus or Dragonstorm (or don't do them as frame combiners) in studio series then there will probably be a non-torso commander that year.
Unless they do the titan/commander swappy thing they're doing in 2026 again, but I don't think they will.
