Yes, it's a common technique.
My old Cisco router did something similar. It had a tiny initial boot ROM, that activated the console and performed some initialization. Then, unless told otherwise on the console, started the primary router image from a much large flash device. The large flash device could hold 2 or more router images, unless you needed all the features.
If things went badly with the router image, you could even reload the router image via initial boot ROM. Clumsy, but doable. Meaning the router was not bricked.
