It applies to all because it would be a bad thing
for a successful completion response to a SCSI task
within the scope of the ABORT/CLEAR TASK SET to
arrive after the task management response indicating
that the abort or clear function is complete.

In general, a SCSI abort
is considered successful if the task completed
before the abort got to it, but it's necessary
to either force presentation of the responses for
such tasks to the SCSI level on the initiators before
declaring the abort to have completed or ensure
that they are discarded if received subsequently
- the latter would be a mess for the iSCSI TASK SET
functions, hence the text you referred to.

Thanks,
