I meanwhile understand that in your case "C-h e" splits the original
window horizontally, i.e. you get 2 windows side by side, not one
above the other.  AFAICT, this was never explicitly mentioned in your
bug report.

In any case, Martin explained the logic behind selecting another
window in this case.  FWIW, I think the existing logic, which prefers
the most recently selected window, is more sound than the one you
propose, because screen positions can be more arbitrary/random than
the MRU order.
