So I was testing out Void Shift on the Beta, (swap health percentage with a friendly targeted player and heal the lower health person for 25%) and it is not yet set to Party or Raid members. When I was accidently disconnected from the Beta & had fallen from my mount with 10k health left, I targeted a random player (with full health) and hit void shift. I went to full health & they dropped down to around 25%.
I can see that being changed.
