Effect of a misplaced root on inferred edit paths. Trees (a) and (b) are identical if the rooting of one or the other is ignored, as would be the case in EEEP, and no edit path reconciliation is necessary. However, LatTrans and HorizStory, which both require a rooted test tree, would be adversely affected by misplacement of the root, since four edits are required to reconcile trees (a) and (b) if the rooting is preserved.
