It is different because St. Basil refers to the transmission of will, with the mirror analogy, a transmission without subordination, since Jesus Christ is the Godhead. He states:
19. … Rather was the Word full of His Father’s excellences; He shines forth from the Father, and does all things according to the likeness of Him that begot Him. For if in essence He is without variation, so also is He without variation in power. And of those whose power is equal, the operation also is in all ways equal. And Christ is the power of God, and the wisdom of God. 1 Corinthians 1:24 And so all things are made through [by, A.V.] him, John 1:3 and all things were created through [by, A.V.] him and for him, Colossians 1:16 not in the discharge of any slavish service, but in the fulfilment of the Father’s will as Creator.
“20. …Let us rather, in a sense befitting the Godhead, perceive a transmission of will, a transmission of will, like the reflexion of an object in a mirror”. Note that the essence of Jesus Christ, is both divine and human. St. Basil makes the further comment:
21. He that has seen me has seen the Father; John 14:9 not the express image, nor yet the form, for the divine nature does not admit of combination; but the goodness of the will, which, being concurrent with the essence, is beheld as like and equal, or rather the same, in the Father as in the Son.
