I think there's just some nuance to the scenario. The pilot wasn't directly on the call, but was participating in the call with the flight supervisor relaying the information.
I'd compare it to being in the room with someone on a conference phone call and they're relaying the conversation to you and them both ways. I would still say you were participating in the call even though you weren't directly on the call.
Also, he did initiate the call so "F-35 pilot held" is imprecise, but not totally wrong. Either way, the pilot was in an active tech support session with the plane engineers, making this one of the most intense tech support calls in history.
