Daniel. I finally got to the grub boot selector with a single escape key hit after selecting the Ubuntu volume from the Mac EFI option boot selector. It works normally for the single Linux installation on the drive. I don' see any reason why it should behave any differently in a dual boot situation. So invoking the grub boot selector from the /boot/efi/System/Library/CoreServices/boot.efi location has no impact on its functionality.
