Tested with AMXX 1.8 and 1.9, on HLDS and ReHLDS, on Linux and Windows, with players and bots. The results are the same.
I detected when mystery damage has taken it says 15.0 that is actually not true cause after I repeat the last damage on myself it multipled by 1/3 so 5.0.
Edit: Updated source code in comment one. That is generating the following logs:
Code:

After a real attack (by a bot to me) (knife stab) I receive his last damage * 1/3 from myself. The first time this extra damage doesn't apper cause I think there is no prev damage in the puffer.
Edit: As I see the damage receiver will be te prev attack's target and not the sender. In this example it is me both but can be anybody else.
