>f someone refers to AD&D, they'e referring to AD&D, both 1e and 2e.
There's no such thing as "both AD&D and AD&D 2e", since they're two different editions. And there's no book called "AD&D 1e". Just look at the covers, and see what the two different editions are called:

Top one: AD&D

Bottom one: AD&D 2nd edition
