It does to me.

Because Texinfo produces filled text on the assumption that it will be
displayed with monospaced font.  The Info format was invented for
text-mode readers, and it uses hard newlines where the line should be
broken.  This doesn't work well with variable-pitch fonts.

Of course, it does.  But most Lisp applications don't bother doing
that, even though the facility is available since Emacs 21.  Counting
columns is so much easier.
