In other words, the Pacific is so wide that cyclones typically curl North before making it all the way across, so it’s unlikely that the same storm would affect both North America/Hawaii and East Asia. Therefore, it’s not necessary to force anybody to give up the name they previously picked.
(The word “hurricane” came from the Arawak people in the Caribbean, while the etymology of “typhoon” is less clear but may have come from China or India. Also, for completeness: “cyclone” is of Greek origin and is used for southern hemisphere storms because the British picked it in the 1800s.)
