Great, as I expected it.

Essentially, yes.

Due to an unfortunate name collision, the package moreutils has a command
that is also called parallel.
GNU parallel, to be compatible, also exposes that behavior, when invoked
with the --tollef option. Otherwise, it is the pure GNU parallel behaviour.
The default behavior in Debian was chosen to be --tollef as moreutils's
presence in Debian predated GNU parallel for some time and to not interfere
with users that happen to have both moreutils and GNU parallel installed.
To be honest, I don't know much about the parallel command in moreutils to
be able to provide a patch for upstream documenting the changes in behaviour
that should be there when the --tollef option is in effect.
(Not that I care much, anyway).
