It matters not what other drummers do or how they place their toms... or anything else for that matter. Placement of bits of kit are entirely a personal thing. Put everything where it is most comfortable to play. There is no right or wrong, everyone does it differently (except those who think that what some famous drummer does must be right for them), and it doesn't matter what it looks like either. Try things in every conceivable position until you find what suits you.
