Oh, indeed. :)

I tried setting it to 20, but cannot see a difference.  My frame is 221
columns x 61 lines tall.  I'm in *scratch* (the only window) and eval

  (display-buffer "diary")
  (display-buffer "*Help*")

step by step, first with the default threshold of 500.  Because I use
split-window-preferred-horizontally the diary buffer is shown in a new
window right of the window holding *scratch*.  Now I eval the second
`display-buffer' and the right window's buffer is replaced with the
*Help* buffer.

With `split-height-threshold' set to 20 I get the same behavior.
Reading the `display-buffer' docstring I think instead of replacing the
right window's buffer it should instead split the left window
vertically, cause that's much bigger (61 lines) than the threshold.
