Utter nonsense.
Mic acoustic sensitivity ranges over about a 30 dB range. A 30 dB larger
signal is going to be about 30 dB less affected by a given level of noise
pickup.
Irrelevant to to Dave's statement.
You missed the relevance of the word "effectively".
No.
The statement is still wrong. The signal level does not ever affect the level of
pickup. It affects the signal to noise RATIO and nothing else.

That's right. Two things are important here - one is the presence of
the word "effectively", and the other is the absence of the word
"level". Put those two factors together, and you have a good
statement, to the effect that pickup is less of a problem on cables
carrying large signals.
