If he does not have another Mac and that he bought Lion for with his own Apple ID he can not buy Lion or Mt Lion with without having a Mac system that can Log on to the Mac App Store.
I am Not sure if it can be done from any other Apple device by logging into the iTunes store or the iOS App store.
I think the only place you can buy, download and install Lion or Mt Lion is from the "Mac" App Store and then only from a "Mac" Computer. As you can NOT log in to the Mac Computer App Store from any other Apple device.
Just like you can't login to or buy iOS Apps from a Mac computer. You must hjave an Apple iOS device to do that.
The iTunes store, completely separate from the "iOS" App store and the "Mac" App store, can be logged into from any Apple device as all Apple devices can download and play music, some can play movies and Podcasts.

Im not saying he can bypass the AppleID verification. He will either activate 10.7 and then continue installing with HIS AppleID, or he will boot from the 10.8 USB Disk which will again ask him for his AppleID, but since he has bought this it will accept it again.
As i said before, the DVD might take some time, it's up to the OP to decide whether he wants to go with it or not.
Edit: I dont really need them to be honest. Since i got the ability to boot from recovery HD/Internet Recovery, I haven't experienced any issues through out these 2 years. And I have re-installed several times.
