I don't think so. The context of the conversation was, as he was weighing out my malted wheat (grain form), that one of his customers complained of the difficulty of milling wheat. He had to take the drill off the mill and do it by hand because the drill couldn't do it. That's when he said that he just throws it in the mash. He does the same with rye. I wish he was talking about the flaked stuff, but I don't think so. Weird!
