From my experience it DOES do that - but only on some of my drives, not others.
That is, some of my drives exhibit the desired behaviour (boot first into the FileVault unlock prompt, followed by the OS X login screen), while others go straight to the OS X login screen with "[Update Needed]".
Why this happens I'm still trying to figure out. I'll do some further investigation and report back.

This is not an option since my Mac is used by multiple users, and I've already maxed out on the password complexity that the other users are willing/capable to accept.
The reality is that OS X passwords that are used multiple times a day - including every time you switch users - can NEVER realistically be as strong as the kind of passphrases you can consider using for FileVault-encrypting a drive that is used only for backup.
This is because the latter only need to be used in a backup test or restore scenario - so they can be ultra-strong, long, randomly-generated passphrases such as "%JHgTil#=qH1j.d6.Ak8t`3C" - which you can store in your credential vault and forget about. Believe me, you wouldn't want to type these in every day!
If your backup drives are taken outside your home, transported, and stored in various locations, I think it is quite a legitimate requirement (for some users) that the backup drives are only decryptable with a very strong passphrase, and NOT with the (necessarily weaker) OS X passwords.
