If you're flying east over the pacific you're originating in Asia. I don't know where the confusion is coming from regarding this. United's statement:
We will reduce our remaining trans-Pacific operation starting March 22, with final eastbound departures on March 25, with the exception of service between San Francisco and Tahiti and San Francisco and Sydney which will have final returns to San Francisco on March 28.
All of these are described as the final flights TO the United States, which makes sense because people want to make sure they can get back to the US from where they are. Therefore there is no March 25 flight from the US across the pacific, because if there was it would land on March 26 and therefore there would be a return to the US on the 26th.
