iSCSI: A bit and followed by separate Status PDU

[Eddy Quicksall <eddy_quicksall@ivivity.com>]

9.7.2 says:

On receiving a Data-In PDU with the A bit set to 1, if there are no
holes in the read data until that Data-In PDU, the initiator MUST
issue a SNACK of type DataACK except when it is able to acknowledge
the status for the task immediately via ExpStatSN on other outbound
PDUs if the status for the task is also received; in this latter case
(acknowledgement through ExpStatSN) sending a SNACK of type DataACK
in response to the A bit is not mandatory but if it is done it must
not be sent after the status acknowledgement through ExpStatSN.

Regarding the "if the status for the task is also received" ... is that
referring to the S bit and A bit within the same PDU or is there some other
case I'm missing?
