If it helps the discussion(s) about aero benefits, two good articles can be found at:

In terms of your direct question - from the 'dynamics' link -
'the amount of lateral force that can be generated by a tyre is extremely dependent on the vertical force acting upon it.
Simply put, the higher the vertical loads on a tyre, the higher the lateral force it can generate.'
So - with more rear downforce, higher lateral force can be put on a tyre, allowing acceleration to happen earlier out of a corner.
A more complex way to look at it comes from the racingline article, which expands on centre of pressure (CP) in relation to centre of gravity (CG).
'anytime the x-coordinate of CG and CP will not be the same, downforce will create a moment that will tend to rotate the car around an axis parallel to the y one.'
So - with an increase in rear downforce (only) the moment when the car rotates (squats at the rear) happens earlier in the acceleration phase of the corner.
