It's correct. The idea is to allow everyone to boot using the uEFI entry point in Linux (or any other OS), regardless of whether they want to run U-Boot or a TianoCore based formware.

This might seem useless today for embedded use cases, but some features are only available via an EFI entry, such as kASLR. You can also invoke Linux directly using the "bootefi" command, as Linux is an EFI binary itself. That way the boot path doesn't become much longer than with booti today.
