That can’t possibly be true. Even if the server integrates all in bound streams into one, doing so takes a non-negligible amount of additional time per user, surely.
The person you replied to was talking about bandwidth, not CPU load.
Imagine a user that only has enough bandwidth for a single stream. If there was a server integrating all other user streams into one, that user would be able to watch it without much problem.
Unless, the clients are built in such way that they down-scale the resolution to part of the screen it would occupy on target computers (based on number of participants) before sending video data. Is any software doing this currently?

Integration has to happen at one point. Whether a server does it or each user's computer.

It's the obvious thing to do - I can't imagine why they wouldn't.
