Niki Prongos, Leroy Bryant, Dara Adeyemi were "now juniors" when they transferred here, so that's wrong.

had they completed their junior year before transferring?

unless things have changed transfers in could bring up to 90 units with them from their previous university so anyone transferring after more than two  years elsewhere would essentially leave units behind

It is common that some classes are not accepted as "Stanford equivalent" and therefore units for those classes don't transfer. Transfers often take a units hit as a result. Hard to imagine it would be a full year's worth of units but depending on what classes the student took it is possible.
