Ok,
the part in Question... his EK2 doc signed by the General on the 10.10.1918... although he was killed on the 4th.
A little bit of research shows the division was pulling back and reforming that week, so I am guessing, he was wounded, the proposal went up to the division, he died, the general signed and whammo... a Posthumous award by error. This is all pre email... so if a Company commander sends a proposal to a Regt commander who forwards it to the division.... we are talking about some time required for the papers to go their way...
best
Chris
