button for multiple instantaneous spells

[scyllel]

Is there any reason why you can't have multiple instantaneous spells fire off with a single onpress statement? I tried doing it like this:

OnPress="target_none target_group_member 1 useability Radiance useability Salvation"

both abilities are instantaneous, but only the first one fires. Is the problem the way the engine works, or the way I've written it?

Thanks,
