Guardian Angel Fountain Death?

I was practicing my Galio gameplay in a custom and I bought like i always do, since the mr boost (ap boost with his passive) plus the GA passive goes really good together. I'm shredding bots and having fun. Didn't die at all up until the nexus was about to die. For fun, I dive on their fountain and just automatically died without my GA even going off. I'm pretty sure the passive for says "Upon taking lethal damage, restores 30% health and mana AFTER a 4 second stasis. Look its a bot game and yeah I didn't want to die. Thinking the victory screen would pop up while reset me living on their fountain. Im not LCS level skill but have been in games where fountain dives have happened. I understand that once my GA reset me I wouldn't have any amount of time to get out of fountain since I was flashless and out of flash range to get off there fountain ( yeah I was that far on it) still Riot has gotten the description for GA wrong. GA doesn't even work if you dive fountain.........Right now they have it to where the fountain turret only targets one at a time. Why not just make it so anyone that goes on enemy fountain gets targetted even at the same time. You are always talking about wanting to evolve Riot. Get the item descriptions right first. Just my opinion. What do you guys think?
