A subvolume can be moved everywhere with a simple 'mv' command.
No, they can not,, try this again with a *read only* snapshot
The topic was about why put the subvolumes/snapshots in another subvolume.
A readonly snapshot can't be moved from its parent (doesn't matter if it is a
diretory or a subvolume). This is true. But the subvolume containing a readonly
snapshot can be moved :
$ btrfs sub crea sub1
Create subvolume './sub1'
$ btrfs sub crea sub2
Create subvolume './sub2'
$ mkdir dir1
$ btrfs sub snap -r sub2 sub1/snap2
Create a readonly snapshot of 'sub2' in 'sub1/snap2'
$ btrfs sub snap -r sub2 dir1/snap2
Create a readonly snapshot of 'sub2' in 'dir1/snap2'
$ mv sub1 sub1-renamed
$ mv dir1 dir1-renamed
