That would mean that ƩFy is not zero... what would that mean?
Of course ƩFy is zero. The resultant force at Y of the rightest pulley is 2/6.... Of the middle pulley is also 2/6....and the right 2/6.... these are the up vectors in the Y direction...the down vector is just the weight....so of course it ends up being ƩFy=0
