Mitzva Ha-baa Bi-aveira And Ee Avid Lo Mehani

My beloved friend the great ilui  הרב צבי משה קנטור שליט"א  asked a fine kashya.

What is the difference between the rule of אי עביד לא מהני [see Temurah 5] and מצוה הבאה בעבירה. The gemara never discusses one rule in the context of the other rule even though they seem to be the same thing.
