Info menu entries' highlighted every 3

[Stefan Monnier]

What was the reason for the change from highlighting the 5th and 9th
menu entries to highlighting every third entry ?
The question is not really about the change in the distance, but
about the fact that there's no upper-limit any more: we happily
highlight the entry number 45, although I doubt anybody will be able
to use this "visual cue" in any way (especially since the only
command that can use the numbering is Info-nth-menu-item which
is only meaningful when bound to keys 0-9).
Why not only highlight '(3 6 9) ?
