That mapping appears to be the opposite of what Apple documents.

The following information is found in the "Apple II SCSI Card
Technical Reference Manual" (APDA #A2G0029) on page 3:

"The Apple II SCSI Card's SCSI ID number is set by positioning a
jumper on a strip of pins. With the jumper positioned across pins 1
and 16, the SCSI card's ID number is set to 7. With the jumper across
pins 8 and 9, the SCSI card's ID number is set to 0. For most
applications, the SCSI card should be set to ID number 7 (jumper
across pins 1 and 16)."

The pin numbers for IDs 1..6 are left as an exercise for the
reader :-).
