All Summon Corpse spells including the new lower level one that has a level 35 cap on the level of the player/corpse you are trying to summon, will summon not only your corpse but corpses of any targeted player that is currently in your group.
I know Lucy shows self targeting however live has allowed you to summon grouped players corpses since the introduction of the spell when Ishva Mal began dropping it in Paw.
Here is some reading on the subject:

I'm sure many of you players remember having to bring coffins to a raid so in the event of a wipe the necros could summon the whole guild.
Necros will remember how kick ass it was when Velious introduced a
robe with this as the right click effect since you could summon the entire guild without using mana.
