Indeed, that's exactly what it tried to be. I prefer to call it a relaunch (without shady 80% premine) than a fork, although there were enough superficial changes (moving decimal point, etc.) to consider it a fork. In practice though, it was mostly just an open relaunch of Bytecoin, instead of trying to pass off the testnet using false claims of a large community with deep web "stores and services" and other lies.
