The reason he can do this is because the single use license is for "Mac OS X" and not for a specific version AND he bought the retail media for Tiger.
IANAL - that is my understanding.
If this was true then I have 4 "licenses" of Tiger?!? - No!
If you have 1 copy of Tiger (not Family pack) you have 1 license of Tiger.
If you want to install it (legally) on another machine, you have to buy another copy. Just because you don't have Panther installed on other machines does not mean you've effectively migrated the licenses.
I'm pretty sure of this from this situation:
Say you already own 3 Macs all running OS X.1 or .2 or .3 (or a combination). Then you go out and buy a Mac Mini, which comes with Tiger (either direct or second hand). It would be ludicrous to expect that you can now legally install that copy of Tiger from the Mini on all your other machines. That would be getting something for nothing - not a common occurrence in the retail world!
Quoting Various Bits of the License:
This license allows you to install and use one copy of the Apple software on a single Apple-labeled computer at a time. This license does not allow the Apple Software to exist on more than one computer at a time,
And goes on to say about transfer:
Updates: If an Apple Software update completely replaces (full install) a previously licensed version of the Apple software, you may not use both versions of the Apple software at the same time nor may you transfer them separately.
i.e. you can't use a previous version of the OS (or "Apple software) that has been replaced by Tiger, on a different system at the same time. - my interpretation anyhow.
