The original post here involved a claim that neanderthals merged straight into modern humans, which is clearly untenable. As far as humans AND neanderthals both being descended from some third party more primative than either, that is clearly nonsensical; the neanderthal has been ruled out as a human ancestor precisely because the genetic gap is too wide and you're proposing that we must therefore be descended from something with an even wider gap.
I disagreed. Now you write:
What do you mean "wrong"?? Your chart shows precisely the thing I claim, i.e. both neanderthal and us descending from something more primative than either, despite the neanderthal having been ruled out as a plausible ancestor for us because he was too primative.
Lets take this a step at a time. You originally wrote:

Here is the chart again showing both H. sapiens and Neanderthal descending from an earlier common ancestor:
