GPIO sink current on nrf52832

The table on:

infocenter.nordicsemi.com/.../gpio.html

specifies: Iol,hdh = max 15 mA for Vdd >= 2.7V.

The graph lower on the page (Figure 6. Max sink current vs Voltage, high drive) specifies around 22 mA for Vdd = 2.7V.

Which one is correct, or what's the difference between the two?

I want to drive a RGB LED using the low power pwm lib. Each of the LEDs needs max 10 mA.
