Summon could be said because the definition of summon is authoritatively or urgently call on (someone) to be present

so you could say they are calling forth the susanoo

they have said that susanoo is the user's guardian deity as in in a manner of speaking they are literally summoning susanoo

But like i was saying. it would be logical that sasuke could atleast use the Yata Mirror and Sword of Totsuka

im not saying a definite but being that Sasuke's EMS has the visual prowess of both sasukes MS and Itachi's MS then it would stand to reason that he could use itachi's
