Title: Meta informaiton for a loop/graph was wrong

Meta information for a loop was based on the input dataset, instead of
the intersection of the input dataset and the result of the loop.
Could potentially cause some optimizations to occur (e.g., removing
sorts/making local) which weren't always valid.
