That's probably because your monitor is larger than my laptop's.

Try doing (set-face-attribute 'default nil :height 290)

If the frame is large enough to fit two windows side-by-side, then the
help buffer will always be created in a new window to the right.

However, if the font size is large enough that two windows do NOT fit
side by side in the frame, then the window is created below. In this
scenario, you get the behavior I described (i.e., if there's already a
window below the current one, it is reused by the help buffer and it
is expanded if necessary).
