AFAIU this will assume ACCESS_GROUP_INNER to appear before
ACCESS_GROUP_OUTER since CHECK-SAME will continue matching at the
column where the previous match stopped, thus have the same result as
written in the same line. If CHECK-SAME starts over at the beginning
of the line  ACCESS_GROUP_OUTER/ACCESS_GROUP_INNER will both match the
same.
