[Bug] Yogg crusher tentacle and judgement

Is the intended interaction for judgement from a holy Paladin to break the channel? Is this not pre nerfed Ulduar?

[Hotfix] (2009-05-14): In the Yogg Saron encounter, Paladin Judgement spells will no longer cause [Diminish Power] from Crusher Tentacles to cease channeling.

Why is it allowed now? This change was made before Yogg was nerfed.
