I've always been vocal about calling out mirrored scores as inequivalent and the like but meh, this seems fine.

I can remember someone playing jackhammer madness by trilling the jacks on one key as a proof of concept. I tried it myself but couldn't figure it out lol

I'd say this is a rare situation where the technique is useful. It's not like double-setup which itself seems ludicrous to practice but imagine what you could do if you mastered using it.
