Yep, you can't do that.
It looks like you're trying to do a combinator attack. There's a direct combinator attack (which is -a 1), or there is a way to simulate a selectes subset of combinator effects using a rule. But you're doing a strange mashup of the two, which won't work.
Either use -a 1 and two wordlists, or use -a 0 and multiple rulesets.
