It's a way to add emphasis on "They did a good job".
We could translate it as
"I'm somewhat biased against BlueOrigin, but BlueOrigin managed to overcome my personal bias with how impressive their launch was".
It's similar to saying "I normally don't like country music, but that was a good song". In that sentence the intended message isn't "I don't like country music", instead it's "I liked that song"
