Today this effect is minimal but the continuous evolution of things that can live on land, and in dryer and dryer places would have noticeably increased this as weathering compared to today. Modern sediment source rock is much more oxidized as a whole that is why today the exchange of CO2 and oxygen biotically has a bigger effect. How much sediment is reworked stuff that is already oxidized increases over time but it is still fairly low at the time. The carbon/oxygen cycle is much more complex than just the two exchanging with each other.
