On an older car, the rear brakes are more likely to have weakened than the fronts?
The other thing I would add is there are not many real life situations where you would have zero traction on three wheels.
Interesting the older V70 in this second vid which has thermo viscous coupling based AWD does okay on the one rear wheel test.....

The viscous coupling systems have limited slip diffs at back like the older 960's had so if one slips it will lock and drive both wheels
