What does

# debconf-get-selections  | grep grub2/force_efi_extra_removable

say for you? That's the bit that's responsible for whether or not the
grub-efi-* package will call grub-install with --force-extra-removable
- look in the postinst file.

grub-install is absolutely called when upgrading grub binary packages -
it's needed to put new binaries in place. update-grub only updates the
grub config file that will be used at boot.

  Getting a SCSI chain working is perfectly simple if you remember that there
  must be exactly three terminations: one on one end of the cable, one on the
  far end, and the goat, terminated over the SCSI chain with a silver-handled
  knife whilst burning *black* candles. --- Anthony DeBoer
