No. Yianni's last year of eligibility is this year, no matter where he attends school. He doesn't get the COVID year of eligibility, because he *wasn't* on the roster that year (nor enrolled in school) (https://cornellbigred.com/sports/wrestling/roster/2020-21). Only those who competed in 20-21 got the "free" year.
The Ivy League changed "4 years out of 5" to "4 years out of 6" due to the COVID year, but it is still four years, and the NCAA free year doesn't apply to him (and Vito and Max Dean, each of whom sat out that year).
