I disagree with the basic premise of this: "When it gets cancelled because a certain person is not there, you are doing the meeting for that person".

One person being the driving force behind making something happen doesn't imply that all the benefit accrues to them at all.

"Just make sure everyone is actually recording what they are missing!"

Except they have no way of recording the opportunity cost - they don't know what they haven't been told; they could be missing something huge, but without a venue for communication they don't find out.

I have to say, I don't think this is great advice.
