At work during reply i cant provide a capx.
The duplicate sprite movement would be disabled and move out the pipe via another method(perhaps bullet object) then lets say your main (controllable player) sprite goes down a pipe(disabling its contol when fully inside the pipe) then you would have the second sprite move out from the other pipe and enable the controlls when its fully out of it giving illusion of the wrap.
I think wrap work for edges of the screen only (exiting the screen on the left side will make the sprite appear on the right side).
Hope that makes thing clearer
