First reverse sweep in a bo5?

I don't remember no tournament that matters (masters or champions) that had a reverse sweep in a bo5, am I forgetting something or is this the first one ever?

Vitality - Fut was a reverse sweep, but that was VRL finals so

in vct internationally, yes. https://youtu.be/KGQe7WGQOVU?t=19603

Yes gc is first.
