Because that description is wrong.  It's more like "in some cases, print
some specified string.  Otherwise, print the number".  The trouble is
that the specified string might be the empty string.  So you hit that
case and print the empty string as requested.  But then examine the
print buffer and see that you haven't printed anything, so you
erroneously conclude that you're in the "otherwise" case, so you print
the number when you shouldn't.  That's why you want a Maybe value
instead of checking whether you've printed anything.
