That's sort of what i thought it was about, but your explanation is superior to what I was muddling through on my own. Unless you are syncing via WiFi while away from your main computer, you're going to be using a lot of network data. Fine if you are on an unlimited plan, not so fine if you are not.
I think you are trying to find ways to make this seem worse than it is when the fact remains it is better than what we have now.
For one thing, you can carry the exact same subset of your iTunes library around on your iOS device as you do now: it will always be there. That can easily be done while on Wifi. If you carry a subset of your iTunes music now you are doing so via syncing selected playlists. It is very simple with Match to download all the tracks in those same playlists to the iOS device.
So so how is having both the ability to carry the exact same music around that you do now, plus the ability to access your entire iTunes library on-demand if you want to, a bad thing?
For years on my iPhone I was carrying around more music than I usually listened to, just to "be safe." Over a gigabyte of music that I never, or rarely, listened to (yet often did not have a song I got the urge to listen). On my iPad and macbook air I barely had anything stored locally. With Match I now have complete access to my entire iTunes library on any device--even my ATV. Plus my iTunes library appears the same across all devices: changes made on one are instantly reflected everywhere else.
If you don't need any of that, or have music in higher quality format than 256kbps, you don't have to use it and everything can remain as it is. But for $25 a year for me it seems worth ti.
Heck I feel I have already gotten my money's worth just from the older DRM'd iTunes music that has been upgraded to DRM-less plus format.

No, I understand (seriously?) how it is supposed to work. However, I do NOT plan on using this since I have no need to do so. Why would I want to have even more space taken up on my hard drive? My explanation was to someone who thought he could replace lower bit rate music with higher by changing his preferences in iTunes.
I don't think the up-converting originally came up just for the sake of seeing at a higher nitrate. I believe it was about Match ignoring low bitrate tracks.
The fact is iTunes match will not even attempt to match anything with a bitrate of less than 96kbps.
I had a few thousand 64kbps tracks that I was just about to trash as the quality "was" so poor. These were legally recorded via internet streaming from a service that was out a decade ago or so--but only at 64kbps. iTunes match would not touch these tracks because of their bitrate.
But I up-converted them all and Match did in fact match more than 90% of them. I deleted the crappy originals and have downloaded the 256kbps versions, which of course sound MUCH better.
So there is a valid reason to up-convert that has nothing to do with thinking you are getting a higher quality song.
