No, its just the regular conjure undead spells, the perk is supposed to give x3 duration to all conjure undead spells but it doesn't. My Reanimate Corpse spell last just as long as my Flame Atronach with the Preservation perk and no Atromancy perk.

So, part way through my necromancer playthrough, I have noticed that the Ordinator perk: Preservation is not working. I doesn't apply the effect to the vanilla reanimation spells, DLC Soul Carin summons, or any modded Conjure Undead spells. I have tried removing all mods except for Ordinator, extracting the scripts from the BSA, load order.
