When you make a cake do you leave the frosting off and still say you're done? No. The fact that he didn't deactivate the switch left the job unfinished and left the cake that was his battle incomplete.
Well then I guess by your definition OOO never had a proper Rider Kick considering it never finished off a monster, even Uva. It didn't finish off that Cat Yummy, then that one where Birth and Him doubled teamed on one Yummy (OOO kicked but it was Birth's Cell Burst that did the job) and then Uva was revived right after he was 'killed'.
The fact is, he did a Proper Rider kick to the monster. He did not however do a proper deactivation which has nothing to do with the kick. This is comparable to baking a cake, putting the frosting on, and then realizing that you baked the wrong type of cake and have to start all over. Oh and not all cakes have frosting on them
Besides, technically he hasn't done a proper Rider Kick yet considering, it's not the kick that finishes off the monster, it's him pressing the switch. If anything, he hasn't done a Proper Rider Kick yet, but a Proper Rider Press :laugh:
