File 
hyracks-fullstack/algebricks/algebricks-core/src/main/java/org/apache/hyracks/algebricks/core/algebra/operators/logical/visitors/SubstituteVariableVisitor.java:

Line 409:         
op.getBranchingExpression().getValue().substituteVar(arg.first, arg.second);
here, you can just do
op.substituteVar(arg.first, arg.second);

Instead, you need to implement the method
substituteVar inside SplitOperator.

So that the operator itself has the correct semantics.
