I looked at a utilities manual for OS/390 2.10. COPYGRP is documented,
COPYGROUP is not.

COPYGRP can be used to copy a data set when either the input data set or the
output data set, or both, are PDSE:
PDSE to PDSE
PDSE to PDS
PDS to PDSE
For unloading groups:
PDSE to PS
For loading groups:
PS to PDSE
If neither data set is a PDSE, the request is treated the as a COPY operation
subject to the syntax requirements of COPYGRP.

That was true the case up to the z/OS 1.13 edition of the manual.
Apparently COPYGROUP was added with z/OS 2.2.
Under "Copying Program Objects (COPYGRP and COPYGROUP Statements),
The V2 editions of the manual have this:
