Oh lawd, they can each use eachothers ballz... I played an actual match of all Syndra vs all Darius, and the allied ones when ulting would use all of the nearby orbs that the others had spawned. We managed to get the max amount for each one after using 5 ultis one after the other with all max orbs, the sixth Ulti used all of them and basically one shot their most Tanky Darius.

It was glorious.
