The reason this matters is that if they get into an orbit in a short test, they need to exit that orbit with some sort of active system. So the statement "we got to orbit" implies a lot more technology development than the current flights actually show. I agree with Scott that Starship can easily enter LEO, but I am not so sure it can exit gracefully.
My impression is they just need to leave the engines on a little longer to get to orbit, then turn them on again with the ship pointed in another direction to get back to the suborbital trajectory they’ve already demonstrated deorbiting from.
The hard part is reentering through the atmosphere without burning up, flipping, and landing, which they’ve already demonstrated multiple times. There’s no additional atmosphere between where they’ve flown and “orbit”.
