I see.
The reason for Sisyphus is the same as Icarus as pertaining to Greek mythology. Icarus tried to fly too high, and thus fell. It equates very well to what we see in the game. Sisyphus on the other hand, was doomed to an endless march whereas every time he seemed to be at the end, he would have to start over. I see that as equating very well to a match-type game in the style of GOIO.
Also, Lobbies of Sisyphus.... applies.
