UMLR — Minor error in ptc-13-09-05

In ptc-13-09-05.pdf on page 9 it says:

Where items need to be grouped they are enclosed in simple parenthesis; for example:

(<item-1> | <item-2>) *

signifies a sequence of one zero or more items, each of which is <item-1> or <item-2>.

I think the word one must be replaces by zero because on page 28 it says:

If the lower bound is equal to the upper bound, then an alternate notation is to use a string containing just the upper bound. For example, “1” is semantically equivalent to “1..1” multiplicity. A multiplicity with zero as the lower bound and an unspecified upper bound may use the alternative notation containing a single star “” instead of “0..” multiplicity.
