I think in this case both will be deleted. If you want to have the match
happen again after the first is deleted you should do the following. 

1. In the rule make the "For all" attribute to false. This will only
execute the rule once. 

2. From outside the rule send the outputs of the rule to the inputs.
This will cause the rule to fire once, match A, B. A will be deleted.
The rule will end, the output go back to input. Next time there aren't
two objects and the rule will fail.

I hope this helps.

Thanks,
Adi
