I interpret this to mean that the database link owned by B1 specifies connection to instance A as user A1 (...CONNECT TO A1 IDENTIFIED BY...)

In essence you're trying to grant privileges to a user on a remote DB, which is impossible as far as I know.

There's really no way around it. B1 has full privileges on all of A1's objects, because B1 _is_ A1 when connected to A. If you want B2 to have privileges on only one of A1's objects, then B2 must connect to A as a different username, meaning a different DB link, and the username must have only the privileges that you wish B2 to have on A1's objects..
