Spoiler for manga:

Yammy is 10 without releasing, becomes 0 upon release. but Yammy told us that Espada's numbers are 0-9. Technically 0 is above 4th and number 10 does not count. So I believe that Ulquiorra's words about the rule includes Yammy... I think

We still haven't seen enough of Yammy's capabilities.
we'll just have to wait I guess
