How did a block have so many generation addresses

[backhash]

hi everyone, bit of a nub question but why did this block have so many addresses do the 'generation' ?

000000000000114a4eb0b052b677caa68d62b982927f956cb5a99f4445154856

I thought in pooled mining, the address of the pool would get the reward and then distribute to the members of the pool? That block looks like somehow all of the miners in the pool got the 'generation'

Thanks folks!
