In memory only the first halfword "counts". But since the area of the halfword
is somewhere not just
2 bytes of the end of the page, and L shows 4 bytes ..
The calling conventions of test and jcl are not different unless during the
last 49 years I have
missed a change (which would have created some not so small incompatibily
problem.)
As S.M. said, everything after 2+length is irrelevant.
