All of them, i.e., all of the aspects of the Partzufim, are connected into a single order, Petach 70 goes on to say, in order to be joined to one another and to be governed by one overarching form of governance, each part in accordance with its own function.
That is, they’re all connected that way in order to function as individual component parts  of a single and whole “Merkava” (i.e., vehicle) that would execute God’s governance of the universe.
 See Da’at Tevunot 124 and Klallim Rishonim 12 for discussions about these component parts, termed koneniyot.
