Exactly. You aren't allowed to bombard planets. Dropping troops is fine. Firing weapons at the surface is not.

It may make more sense to you if you consider the similar clause for not using plague bombs.

It is not said anywhere that this clause does not apply to this very empire only but is galaxy-wide instead. It has to be detailed in the treaty clauses window. Same applies to plague bombs.

As IRL, one must not abide by the Geneva Convention rules against enemies who have not signed it themselves. And no, "it's easier to code it this way" does not cut it .
