Here are diagrams of both ends using disaggregated media, with 2 UAs each, each UA handling two media streams.  The first diagram is "near-end managed", where each end has a UA managing all of its UAs.  The second diagram is "far-end managed", where the far-end UAs are aware of the aggregation.

(This is fixed-width ASCII art.  You may have to copy it to another tool to see it correctly.)

       "near-end managed":

        ----                                 ----
       | UA |\\                           //| UA |
        ----  \\ stream 1       stream 1 //  ----
      stream 2 \\                       // stream 3
                \---- ............. ----/         
                | UA |.............| UA |          
                /---- ............. ----\        
      stream 3 //     .............     \\ stream 2
        ----  // stream 4       stream 4 \\  ----
       | UA |//                           \\| UA |

        Alice                                 Bob



     "far-end managed":
