I understand as he requests "AND" condition.

$ mkdir a b
$ touch a/x.a a/x.b b/x.a b/x.b
$ for file in */*; do echo x >$file; done

Current result:
$ grep --recursive '--include=*.a' '--exclude=b/*' x .
./b/x.a:x
./a/x.a:x

Request from him:
$ grep --recursive '--include=*.a' '--exclude=b/*' x .
./a/x.a:x

It means "*.a expept b/*"
