No, this person is Yoti, the poor neighbor. This sketch even appeared before the character Arturo was designed. Obviously, Ricky and Arturo cut in line. Poor guy, he was supposed to be the second homeless man to sleep with Liz. He was supposed to be the protagonist of Homeless 4.
Since yoti lost the vote to old Berto, it's clear that Zetto could change the plot and rearrange the story order at any time.
