I assume it used the phrase "moot point":

moot point. An issue that is subject to, or open for discussion or debate, to which no satisfactory answer is found; originally, one to be definitively determined by an assembly of the people.

I can't watch the video right now but I think that covers the standard use of "moot point", it's sort of interesting that it ends up being used to mean the opposite of what it seems like it should mean from the dictionary definition.

...used the word "mute" when she meant "moot."  Our conversation:

HER:  "It's not debateable.  It's a mute point."
MICK: "It's silent?  It's a silent point?"
HER:  "No, it's a mute point."
MICK:  "It's a point that doesn't speak?"
HER:    (exasperated).  "NO!  It's a mute point!!"
MICK:  "Do you mean a moot point, basically a purely academic point with no real meaning in this context?"
HER:    "Yes, that's what I said, a mute point."
