This was very sad when it stopped working as it was one of the very last gasps of the old timey "call United and add any segments you like and they'll reprice it while keeping the existing space" situation we used to have.
And for many carriers, since the ticket had to be reissued, you ended up with an invalid ticket. After many complaints, UA told agents not to try.
