Why is not Function SubstituteWithIndex() able to detect common columns between its operands that could be used for join?Please guide and prompt the reasons for such errors.

However, if you add one more line of code, it will become a virtual table, and then add an index column to calculate the table，the result is correct result: Please give me directions when it's convenient. Thank you
