how does backgournd summon objects?

[AdiDidIt]

Now 1st & 2nd ball move towards each other. If the background is correct, both balls should touch each other EXACTLY when the balls go into an activation frame.

they have the correct type.
of what I understood, the balls moves one forward and one backward and the move again to the middle of the Z-axis. if its the correct map they will touch each other and if the map have Z-axis bigger the the balls wont touch each other?
