Which is the same thing. You've also heard them called rockstars or x10 before. They are referring to the same folks, but calling them "easy to manage" is a hilarious statement.
Characteristics like "Stay optimistic at all times", "Make people feel excited and energized", and "Behave in a completely authentic way" are not really things I associated with rockstar/10x engineers (which is also a complete BS label for different reasons).
