Yes, the developer tried to backtrack later in the call...
You say it was later in the call, but it was an immediate request for clarification and then reworded and clarified once that statement was made. There wasn't some long back and forth where the developer finally relented and changed his mind.
If anything, the immediate response of "No, no, sorry. I didn't mean that to-" seems to indicate that he wanted to clarify what he meant.
And "if you want Apollo to go quiet" isn't the original quote anyways, not sure why you had to paraphrase but pretend otherwise.
