Nothing fishy at all - there is an optimization for certain modules (primarily apt and yum) where items are combined into a single execution. This makes these modules way more efficient, since the underlying package management systems are able to handle a list of package names at once just as easily.
But yes, the bug appears to be that some later conditional check is incorrectly being evaluated to make the task be skipped rather than run. As Matt mentioned above, there is a per-item check with the conditional to remove individual items, which I *believe* should be the only conditional check when the items have been merged into a list like this.
