LSM9DS1 Startup Power Sequencing. Problems inherit in not abiding.

I would like to know if bringing up both the Vdd_IO and Vdd lines at the same time on the LSM9DS1 is hazardous for the unit or problematic for its functioning. Why must the rails be brought up in sequence and what problems might I face if I bring them up at the same time?

I have a slew rate controlled switch, but my lines to Vdd_IO and Vdd are tied together. Before I do the board rework I was curious what problems I might see if I simply brought both lines up at the same time. 

Any insight is much appreciated.
