This value SHOULD NOT have an effect if each Set of the Job consists of one sheet. The "output-bin" Job Template attribute should be used instead,  specifying one of the 'stacker-NN' keywords (e.g. 'stacker-1').

FWIW, PWG 5100.2-2001 says:

‘stacker-N’: The output-bin that is best identified as the stacker with values ‘stacker-1’, ‘stacker- 2’, .... A stacker is typically used to collate sheets within a single document (not to be confused with collated copies in which document copies are collated within a job - see the description of the ‘separate-documents-collated-copies’ value of the “multiple-document- handling” attribute in [RFC2911] section 4.2.4). The correspondence between the ‘stacker- N’ keyword and the actual stacker in the device is implementation-dependent, as is the number of stackers. If this group of values is supported, at least the ‘stacker-1’ value MUST be supported, unless the system administrator has assigned names.

For client implementations that require distinct keywords for each possible value, say, for localization purposes, it is recommended for interoperability with other vendor’s Printer implementations that ‘stacker-1’ to ‘stacker-10’ keywords be represented.

So basically this is one big "implementation-dependent" can-o-worms that doesn't use the words "jog" or "offset" but really means that, because how else are you going to "collate sheets" in a single output bin? :/

The "printer-output=tray" attribute (PWG 5100.13) includes the optional RFC 3805 prtOutputOffsetStacking (offsetstacking) element which will tell you whether a particular output tray provides a jog offset for each Set.  That might be something to update in NODRIVER to make it conditionally required or recommended (at least) for trays that support offset stacking - the possible values are 'other', 'on', 'off', or 'notPresent'.
