Marc -

The IBM quote describes what happens in the general case with
Archive: that the Owner is assigned as the invoker of the Archive
command - rather than the owner as seen in OS file system
attributes.  (This differs from Backup, where the assigned Owner is
always taken from the OS file system attributes.)

In the unusual case where the customer alters the dsmc binary to make
it setuid root, then invokes that as an ordinary user, the Owner is
assigned as the real invoker of the Archive command (not root).  This
tracks with the User Name as reported in the 'dsmc Query SEssion'
command, under the same invocation circumstances.
