It means that your tires have lots of grip. When you accelerate that quickly, the squealing tires are trying to grip but the grip is being broken. That's why often you hear that long squeal before the bang in wrecks--someone's hitting the brakes hard but the car has so much forward momentum the tires can't keep their grip on the road.
E could probably give you a better scientific description of the physics.
Since the Subaru had AWD, all 4 wheels moved at the same time, which meant with the same hard acceleration, you didn't have 2 wheels moving and 2 tires getting pulled forward before they start rolling. You can still get that squeal with AWD or 4WD if you have very very grippy tires and accelerate hard enough, but it takes way more force to get to that point.
