I have not, however, noticed that it allows pointing higher.
I don't know why you would think that the jib would make it point higher. A jib makes a boat point LOWER than a unirig....
In my case, although I mentioned some experience to indicate that the jib did not allow pointing higher (and the original question included wondering if the jib would allow pointing higher), that "why" part is easy to answer: general ignorance of the principles ;-)
But, at least I now know that my experience wasn't due to poor technique! (And since that is generally the answer, a different one is welcome!)
