 Review comment:
   Yes, you're right, it's my mistake, of course "downstream" should be used.

 Review comment:
   A filter node requests more rows than its consumer requests from the filter 
because the filter filters some of them) a small buffer is used to hold the 
difference till a next portion of rows is requested. The same is true for other 
nodes, where a node requests from its input more rows than it's requested from 
the node itself.
