Note that this logic doesn't work if clients on a protocol version greater than 78 try to join (the code never reaches the inner if statement). In addition, you may want to limit it to 74, 77, and 78 to prevent people on the intermediate 13w36a, 13w37a, and 13w37b versions (protocol versions 75 and 76) from joining. I'm not sure if there were actually any protocol changes between the versions, but the snapshots might behave oddly since they expect new terrain, etc.
