There is 4 replies because of the following:
NodeA <--> NodeB <--> NodeC
- NodeA sends echo request destined to Node C to the relay NodeB
- This request will reached NodeB and NodeC
- NodeB forwards it to NodeC
- This frame will reach NodeC which will reply to it (REPLY 1)
- This reply will reach NodeA and NodeB
- NodeA gets the first reply
- NodeB forwards the reply to NodeA (REPLY 2)
- NodeA gets the second reply
- NodeC replies to it (REPLY 3)
- This reply will reach NodeA and NodeB
- NodeA gets the third reply
- NodeB forwards the reply to NodeA (REPLY 4)
- NodeA gets the forth reply
