You have a problem because you need to pick sprite 2 in this case, so after grabbing co-ords you need to set position of a sprite 2 if I'm understanding it correctly. For this you need to run the co-ords through a function anyway, or make a second event. Unless sprite 2 is already known somehow then you can pick the correct instance at the start of the event with sprite 1. You could do it in one event in theory which is efficient.
