Description

Consider the following tree:

LogicalAggregate[groupSet=$1, ...]
  LogicalUnion
    Input

When the rule is applied, the top-level Aggregate receives the same group set as the original Aggregate, which is wrong because it points to an incorrect attribute.

LogicalAggregate[groupSet=$1, ...] // <- wrong
  LogicalUnion
    LogicalAggregate[groupSet=$1, ...]
      Input

The correct plan should be:

LogicalAggregate[groupSet=$0, ...]
  LogicalUnion
    LogicalAggregate[groupSet=$1, ...]
      Input
