I think the idea is allowing the turbo to do more of the compression work is more efficient...if you crank up boost, you end up with more excess pressure at the exhaust. If you run more boost but fiddle with the intake timing so that the piston compresses less air, then you can have more of the energy required for compression come from the wasted exhaust impulse energy that the turbine can collect.
