Describe the bug (required)

Forget to handle xor:

 if (condition->isLogicalExpr()) {
    // Case1: OR Expr
    if (conditionType == ExprKind::kLogicalOr) {
      return true;
    }
    // Case2: AND Expr
    if (conditionType == ExprKind::kLogicalAnd &&
        graph::ExpressionUtils::findAny(static_cast<LogicalExpression*>(condition),
                                        {ExprKind::kRelIn})) {
      return true;
    }
    // Check logical operands
    for (auto operand : static_cast<const LogicalExpression*>(condition)->operands()) {
      if (!operand->isRelExpr() || !operand->isLogicalExpr()) {
        return false;
      }
    }
  }
