I'm happy that CSB made that look easy to you, but I encourage you to compare CSB:
with Hollywood Brass:

or the Spitfire Studio Brass version which was deleted.
IMO what makes the CS series great is that the legato transitions work right alongside the rebow/retongue transitions and the "start of a new phrase" note attacks. Thus, you can have a phrase where some notes are slurred, repeated, or played straight, and it all works together creating a deceptively easy-looking performance. In effect, there are a lot more options under the hood than it looks like from the GUI...
