Another way of looking at it is:
Someone has helped you without them expecting anything in return. Also, you may not be able to do anything to return the favour to them. So you try to help someone else without expecting anything in return from this 2nd person because the 1st person did the same for you.
In other words, you cannot pay back the first person for their assistance, so instead you offer assistance to another person as payback for what the 1st person did for you.
