Need Clarification in EEPROM Functionality why FTFC->FCCOB[3] using as FCCOB0?

Hello Team,

I was reading the document "AN11983 Using the S32K1xx EEPROM Functionality" for memory partition.
What I found in page no. 7:-

FTFC-> FCCOB [3] = 0x80; /* FCCOB0: Selects the PGMPART command */
FTFC-> FCCOB [2] = 0x00; /* FCCOB1: No CSEc operation */
FTFC-> FCCOB [1] = 0x00; /* FCCOB2: No CSEc operation */
FTFC-> FCCOB [0] = 0x00; /* FCCOB3: FlexRAM loaded with valid EEPROM during reset sequence */

Just want to ask,
why FCCOB0 will be modified using FTFC->FCCOB[3] not FTFC->FCCOB[0]?

means why all the index of FCCOB is not correspond with the same number like FCCOB0 to FTFC-> FCCOB [0] and FTFC-> FCCOB [1] to FCCOB1 like that?

 PetrS‌ Kindly assist?
