Ah I had not considered snapshotting just /usr before. Thanks for the link, it makes a lot more sense now!
In short: because having things in /usr is equally compatible, and makes some useful things like atomically snapshotting /usr to snapshot all executables, mounting /usr readonly, etc. possible.
