Geoff Johns during his Action Comics run also tied Brainiac with Krypton...as part an invasion as he collected and shrunk Kandor. General Zod commanded the Kryptonian forces that successfully repelled Brainiac (before his fall from grace and imprisonment to the Phantom Zone). It's very possible that they've used this for MOS as well.
