You're not going to overrev one of these things. The lack of any direct mechanical connection either between the gear lever and the gearbox (which in an automatic transmission is usually a planetary gearset, not a traditional gearbox) or between the engine and transmission means it isn't going to happen.
You can blow past a rev limiter in a traditional manual transmission and blow the engine by shifting into a gear too low for your speed. Since the shift lever is directly connected to the gearbox, it HAS to take the gear you select. Since the clutch is connected to your pedal, it HAS to lock the transmission to the crank when you let off the pedal. Thus, downshift to second at 70mph in most vehicles, and PRESTO.
In the WK2, you're dealing with an automatic running through a torque converter. When you move the shift lever in manual mode, you're telling the computer what you want it to do. The computer can say "screw you, buddy, that's going to wreck my stuff but good if I obey," and just keep a higher gear if you try to select a gear that could blow the engine. Sure, you may feel a jolt as the engine revs up to where it needs to be for the selected gear, but you aren't doing irreversible damage; the computer won't let you do it.
