This is the opinion of the Mechaber, who is nowadays considered the 
"Mara De'asra" of the whole Eretz Yisrael.  But in his day he was not so 
considered.   Yerushalayim had its own rav, the Ralbach, who holds 
differently; he holds that Seudas Purim and Mishloach Manos should be 
performed on Shabbos, and thus there is only a 2-day Purim, not 3 days.

I assume that in his day the Sefardi community of Yerushalayim followed 
his psak and not that of the Mechaber in Tzefas.  I wonder at what point 
the community practice changed to that of the Mechaber, and whether this 
was influenced by the arrival of new immigrants who challenged the 
existing minhag based on what is written in the Shulchan Aruch.
