Actually "nushi" can be written with the same kanji as "aruji" so basically there are no difference in the meaning. It's rather typical of Japanese language, one character with a bazzilion different readings. He adds 'sama' tho, so Kogi here takes the formality one step higher.

As per why... well, it's like some people call their father "Pops" and the others "Dad" :) also because Kogi usually uses the more polite speech pattern...
