For one Product line, the crossing between ABS and PBS is standard. For two projects of the same Product line, the changes are the Zones.
In the picture below, ABS and PBS tree structures are projected on the axis of the square. We can see that the triplet {ZBS, PBS, ABS} forms one Task. We can choose the level that we need on each tree structure to form one Task, for instance ABS level #2, PBS level #2 and ZBS level #1.
As shown in the WBS matrix, we can assign several ZBS elements to the couple {PBS, ABS}. In other words, some process (ABS) associated to one Product (PBS) can be repeated in different Zones (ZBS).
