Yes, the target must be KO'd with pursuit for the bug to happen. As for why I think it's worse, the list above says that the entire battle gets glitched, while all that happens in Platinum is a simultaneous occurrence of all weather conditions.

It's not exactly like that in Platinum. People say that, but that's just part of it. Each weather condition individually (including rain/sun/etc.) damages all Pokemon in play. But they will either say their ability hurt them (e.g. 'Charmander is hurt by its Blaze!') or that Sandstorm did.
