I just skimmed part of the report[1]. I don't see anything indicating "Ultra-low SAT scores are a plus!" There's nothing indicating that it's advantageous for an individual to get a lower score.
It does seem to show that black and hispanic students seem to have a lower admission standard for SAT scores. But I can come up with a couple hypotheses for why we might see this data even if the admission ignores race:
1) The admission might largely ignore SATs already. If that's the case, and if black and hispanic applicants have lower SATs, then it it would be expected that black and hispanic accepted students would also have lower SATs because nothing is really filtering out low SAT scores, they're just passed through unfiltered.
2) The admission might have a lower SAT standard for students from low income families. Black and hispanic students might be on average lower income, and thus on average be aided by the income-based standard policy, even though students' race is actually not taken into account.
