I'm pretty sure the policy of full deduction after achieving candidacy applies to every non-resident student, since it is on its website. However, in my case UCSD has given out information in chunks, perhaps unintentionally. First I got the letter I assume every admit got, whether domestic or international. I emailed back with the inquiry about funding, and got the revised letter awarding first three semesters' non-resident tuition. I emailed back, again, with the question of whether the said policy applies in addition to the funding package, and got an affirmative response.
In other words, I don't think you have much to worry about, assuming different individuals' funding packages don't differ wildly. However, either you'll get this information in your official admission letter, or they have to be specifically asked to tell you.
