This is not what the document stated. Here is the quote about "lowering the bar" in its original form:
> Hiring practices which can effectively lower the bar for “diversity” candidates by decreasing the false negative rate
The author deliberately narrows the scope of this sentence stating that the hiring practices decrease the false negative rate, not increasing the false positive rate. Stating that the false negative rate is lowered for diverse candidates is to say that qualified, non-diverse, candidates are rejected at a greater rate than qualified and diverse candidates. It is not stating that unqualified, diverse, candidates are accepted at a greater rate.
