TUSB2E221: TUSB2E221 Power rails ramp time spec question

Part Number: TUSB2E221

Hi Ti team

Here is a description about the tusb2e221 power rails in the SPEC,which is 'Make sure the maximum VDD3V3 and VDD1V8 ramp time to reach minimum supply voltages is 2ms.'

It means VDD3V3 ramp time need less than 2ms and VDD1V8 ramp time need less than 2ms,or is it the total ramp time from the first rail powering on to the last one assertion?
