Your second FCOM quote has probably not been updated to reflect the change.
Thanks Captain...
VERIFY POSITION is still being mentioned in the FCOM along with IRS POS/ORIGIN DISAGREE. This is on the B737MAX and B737NG FMCU14.0. With U10.7 VERIFY POSITION message has been enhanced as you mentioned. The enhancements include
- VERIFY POS: FMC-FMC
- VERIFY POS: FMC-GPS
- VERIFY POS: FMC-RADIO
- VERIFY POS: IRS-FMC
- VERIFY POS: IRS-IRS
- VERIFY POS: IRS-RADIO
- VERIFY POS (On GND Only)
Both IRS POS/ORIGIN DISAGREE and VERIFY POSITION appear on GND as per FCOM. Then what's the difference ?
