Correct, but you can have d e f g ..., so you can have two different disklabel partitions for each version of /, /usr and so on, and have a choice of kernels stored on /dev/wd0a set to mount root from the relevant incarnation of /. (there may be another way that doesn't involve custom kernels but it doesn't come to mind right now).
