Please explain what this represents and why they are exactly the same thing represented differently. Why are A and D interchangeable?

A cladogram is a physical representation of the relative relatedness and connectivity among different organisms with the course of evolution. The diagram starts from a reference point as a single line and keeps on extending and branching depending upon the extent and nature of distribution.
Here, it is important to note that whereas parallel lines do not indicate similar extent of evolutionary aspect since the line appearing early demonstrates early evolution and that appearing late demonstrates late evolution. Hence, these lines i.e. A and D are not interchangeable.
On the other hand, non-parallel lines emerging from a single crossing demonstrate co-evolution and can be inter-changed with each other, hence B and C can be inter-changed.
