Clones are the same node — Leo 6.7.2 documentation

# Clones are the same node

Changing the headline or body text of a clone changes the headline or body text of all other clones of that node. Furthermore, changing any descendants of a clone, including inserting, deleting or moving nodes, results in the same changes being made to all other clones.

In fact, all clones of a node are actually the exactly the same node, so any change to one clone inevitably affects all other clones.
