Yeah, it also means that the N64 had 64 bits and they named the game Mario 64 also, Mario 128 was going to be the name of Galaxy because the Wii has a 128 bit. To answer your question that, no, its the sequel to Mario Sunshine.
mario games shouldn't even have sequals its not like the next game will gave a broader storyline then the last which will answer some of the riddles left behind in the last storyline and its not like your continuing a adventure and continuing a storyline, the princess gets kidnapped you save her blah blah no need for sequals lol I just hope its a good game as I'd love to play a good mario game at launch I had to wait ages to play a good platformer on the GC
