Well, I would imagine that it would certainly draw admissions’ attention if the RD school has a program that is very similar as the legacy school, for which the candidate is a strong candidate. This after all lies at the heart of what ‘yield protection’ is all about. I do agree that it’s a bit of a risky move on the part of RD admissions. And as momofboiler1 above noted, legacy status tend to mostly help ED applicants, who by virtue of applying in RD to another school means the applicant was not accepted via ED at the legacy school.
