The hanmi posture in Aikikai is actually the shizentai - meaning natural posture - migi with the head and center to the left and hidari the other direction.
Shoji Nishio shihan explained that the nage should always face the tori in a shizentai kamae (neutral post). The nage should assume a stance after the attack has been initiated.
"the nage face the tori". Perhaps Nishio Sensei uses "tori" to mean something other than the normal use.
In seriousness, you should be aware that Nishio Sensei's aikido isn't necessarily representative of all the Aikikai.
The Aikikai is an organization under which there is a plethora of expressions of aikido.
