I \think/ the following is meaningful and right about
http://www.openannotation.org/spec/core/20130208/multiplicity.html#List

1. The turtle example doesn't specify that the list ends in rdf:nil
although the picture does.  I think you need something like
  rdf:rest [ rdf:first <selector2> ;
                  rdf:rest rdf:nil ]
as the end of <list1>

2. Well, the spec doesn't actually require or even suggest an oa:List
should be terminated by rdf:nil,  but IMO it would be a good help for
consumers.  Maybe those looking at the rdf ordering problem already
have discussed this issue.
