The apparent Microsoft policy is that every interview pool “must include at least one external African-American, Black, Hispanic, or Latina/o and one external female candidate”. Your counterexample is “every interview pool has to be
entirely white.”
I was originally going to write that you’re playing the “I’m technically correct” trick here, but I don’t think your argument actually rises to the level of technical correctness. Setting aside the debate over whether the former policy is desirable, it is clearly not the same as the latter policy. If Microsoft had said “everyone interviewed cannot be a white male,” or even “most people interviewed cannot be white males,” then you could more credibly try to make the case you’re aiming for. But they simply didn’t.
