Power supply loop

Hi 

    When we test the power supply loop, usually the standard is to look at the phase margin and gain margin, the above figure is in line with the requirements, but the phase curve at the high frequency has obvious fluctuations, and passes back and forth through the 0 point, may I ask if this has any impact? How do you explain that?

thanks
