I think it is fixing a bug, there is a comment in the code which
mentions that 'used_targets will become unavailable in future passes.
This limits some opportunities for multiple source nodes to share a
destination'. As per this comment, it was intended to share a node as
demotion targets with some limits but the code limits not some but all
such opportunities as no common node can be demotion targets for
multiple source node as per current code.
