Does we interpret this correctly when we say: this antenna is parallel

Does it mean that:
  all main mission antennas are in the same plane, but w.r.t. to each
  other 120 degrees turned?
  are the other two main mission antennas 120 degrees tilted w.r.t.
  the satellite-nadir line? Most pictures of Iridiums suggest this.
