You can have an alt account, and Sinister Magnus is still around, you just can't be on the leaderboard more then once. So SM is presumably the alt of someone who is already on the leaderboard. Similar to StarCraft a GM might want to prep openings without revealing that's what they are doing, so there are reasons for having alts but that applies more for longer time controls rather then blitz. Generally GMs do their prep with a small and usually secret team before a big tournament.
