For confirmation and generalisation.
In this simple situation, the line component is matching points placed into 2 trees A and B.
A possesses the following branches:
B possesses the following branches:
The line component matches the first branch from tree A with the first branch from tree B. And the second branch from tree A with second branch from B regarless of the fact that the first branch of A has the same path as the second branch from B.
Can this be generalized ?
In other words, that matching at the branch level depends ONLY on the order in which the branches appears in the list of tree paths.
