If you look at the parent tx they aren't some long mined unmoved coins. Someone create a bunch of 50 BTC outputs. I can only think of one reason and that would be to freak people (who can't follow the blockchain) out.
I can understand someone wanting to hold their bitcoins in blocks of 50, as 50 is the original block reward.
Not sure why that makes it special or whatnot, but I can see why some might do such a thing.
EDIT: of course, in this particular case, I think some sketchy shit is going down.
