Corrective training for the wrong person. Every time I hear a case like this, I'm reminded that when something like this goes wrong, it's usually the fault of something that failed prior to getting to this stage. The problem isn't that this person pressed the wrong button. The problem is that the wrong button was allowed to be pushed in the first place.
Normally I'm down with that, but I think there are some ground-state base cases where you have for perfectly sound reasons penetrated all the security and safety affordances and simply must be careful. "Make sure you've got the right power button before pushing it" is probably one of them. There's not much you can do about that. Maybe not zero, but not much, in a context like this where many servers are being updated, because, again, whatever protections you may have had in place have already been bypassed.
Similarly, when push comes to shove you'll never be able to eliminate the needs for somebody to jump to root on some server, at which point, well, be careful is all you've really got. Hopefully you've built some good habits into your fingers.
