I don't quite understand the Extended Donor Criteria in renal transplant

I don’t quite understand the Extended Donor Criteria in renal transplant. What does it mean by S.Creatinine >= 1.5mg/dl?

Why doesn’t S.Creatinine>2mg/dl qualify as an Extended Criteria Donor, while S.Creatinine>1.5mg/dl does qualify?

Isn’t >2 also >1.5?

(Referring to the Question solved at time 54:40 in Transplant surgery video, Marrow edition 6)

Thank you sir.
