I heard somewhere that AWD is really just the front right tire and left back tire working giving you the benefit of front-rear-left-right tires. Is there any truth to that. The reason I ask is because I bought a new subaru and the front tires came new but the rear are a bit used. Wouldn't that skew things up?

AWD puts power to all 4 wheels at the same time. To allow for differences in wheel speed (on corners, etc), a differential is normally used in the centre, as well as in the middle of each axle. The reason your rear tyres are worn is that they weren't rotated correctly. Since the front tyres have to deal with power, braking and steering, while the rear tyres only deal with power (steering isn't a strain on rear tyres), the front ones will wear out fastest. So they were replaced first. Rotating the tyres gives you a little more life from the tyre, but it also ensures that all 4 tyres wear out at the same time.
If the rear tyres are very used - get the dealer to replace them for free - since they shouldn't have replaced just the front. If they're only a little different, it probably won't matter, since the new ones will wear down faster (since they're on the front.) When they are as worn as the rears, start rotating.
No vehicle has just one front and one rear tyre giving power.
Good luck!
