They don't make the same power and torque at the same time, either one of the engines will be software limited to keep the power and torque at the rated values to suit what they want to do. I couldn't find the graphs for the 330e and 530e but look at the 740e on page 27.

At 1000rpm there is a 250nm difference between the petrol engine only and the two engines combined. But for most of the rpm range it is only 100nm and at 6500rpm it is only about 75nm.
Similar story with power, the gap between the two lines varies with a gap of about 35kw to about 50kw total. But remember that in the 740e if the electric motor only is working it can be producing 83kw and 250nm, a slightly different spec again.
