From your reading, it follows basically.
But.... the OP mentions *Ultegra* STI levers, not Dura-Ace. And a '9-speed' Ultegra derailleur. They
don't mention if they want to shift over 8 or 9 cogs. Without that information, either one of us
could be right.
If they want to shift a 9-speed cassette, then they should read what you wrote.
If they want to shift an 8-speed cassette (not Dura-Ace cassette? I'm not certain), then the levers
and derailleurs will work fine.
