Comment (by tscrim):

 This is not at all clear from the note-block (and the `is_subgraph` and
 "induced" in graph theory might carry a slightly different meaning than
 I'm used to when looking at posets). If this is to respect the labels
 (which I think will be unexpected behavior to the average user), you
 should explicitly state this and give examples comparing the two methods.
