It is not going to be linited to 1 ply but it is going to be limited because the program is losing 5 minutes for every move that it take back to the opponent so if it take back 40 moves then it is going to lose 5*40=200 minutes and this say losing on time. If a program does many tactical mistakes then it is going to lose but if a program is a better positional player and does one tactical mistake for 40 moves then the take back is going to help it.
