REVOKE not honored

[rich]

host1$ mysql
mysql> # create database test, create table t with field f, insert two rows.
mysql> grant all on test.* to 'rich'@'host2' identified by 'dummy';

host2$ mysql -h host1 -urich -pdummy -Dtest -e 'SELECT * FROM t;'
+-------+
| f |
+-------+
| rich |
| test2 |
+-------+

***OK, this is as expected.****

host1$ mysql
mysql> revoke all privileges on test.* from 'rich'@'host2';
mysql> show grants for 'rich'@'host2';
+-----------------------------------------+
| Grants for rich@host2
------------------------------------------+
| GRANT USAGE ON *.* TO 'rich'@'host2' IDENTIFIED BY PASSWORD '...'
+-----------------------------------------+

**** OK, so far, BUT ****

host2$ mysql -h host1 -urich -pdummy -Dtest -e 'SELECT * FROM t;'

STILL gives results - there are now no privileges for rich@host2 on database test, but the user is able to receive the data!

I've tried FLUSH PRIVILEGES, I've even tried restarting the server; same problem exists. Somehow MySQL still thinks rich@host2 should be allowed access to test db.

Any help? I'm going mad here...
