That's far too much turn for a basic Wing. If you're moving along the line of dance in promenade position, the lady can turn between 1/2 total (to end backing line of dance) or 5/8 total (to end backing diag center). Her body will have turned slightly farther to accommodate the outside partner position, but nowhere near a full turn.
The man is pointing toward line of dance on the first step, then has either no additional turn, or 1/8 turn through the feet thereafter. Most of the turn is done through the body. He begins rotated to the right of the foot alignment (due to promenade position), then ends rotated to the left of his foot alignment, to bring the lady to left outside partner position.
You might be able to push the limits a bit beyond the basic textbook recommendation, but I don't see a full turn being possible without additional syncopated steps for the lady. Actually, there's a name for this: A Running Wing.
Assuming you're talking about a basic textbook Wing, 1/2 or 5/8 is appropriate (albeit body more). Man typically follows with a forward step along line of dance or towards diag center.
