It seems interleave was required an gfs2 and ocfs2 clones:

  interleave (default: false)
  If this clone depends on another clone via an ordering constraint, is
  it allowed to start after the local instance of the other clone starts, rather
  than wait for all instances of the other clone to start?

Now it behaves as expected when the node2 is set online:
