Evan, I have been able to reproduce this issue using a regular 10.10 and 11.04 Beta Live CD. The problem is still present in natty (ubiquity 2.6.9).
The action of installing to a USB disk can only be done from the advanced partitioning screen. If you use the automatic or "smart installer", installing to sdb will install the MBR to sda without giving an option to change. After a reboot the MBR will boot from the internal drive and unless the USB drive is present GRUB will fail. Booting from the USB stick will fail as there is no MBR on that disk. This is a major problem as USB creator is nice but does not offer all the possibilities as a full installation on an external drive.
