Potion Master overiding a GA heal?

[ImANoobie123]

I was a Guardian Angel and I healed my target n1.
I died that same night but I STILL HEALED MY TARGET.
My target died via a PM but I protected my target with a GA heal.
I might be wrong and this is just a game mechanic
(I left the game and the only screenshots I can give you is the chat log that I healed my target, which I no longer have)

Was it seen in the chatlog that you as GA watched over your target?
