Yeah, actually I have noticed and was well aware of it when making my comment. The topic of this particular comment thread, however, was specifically about the first graph since the mentioned link's validity was being "defended" by saying the graph was not an "inheritance / 'paternity' graph".

In fact, I could have also mentioned myself that the link was taken off the second graph to further my case that it was just plain wrong. The only reason I did not was because I thought it was something so obvious it would not be necessary to state it.
