I think it is the following condition from CheckHelper::CheckDefinedOperator in lib/Semantics/check-declarations.cpp. I suspect this happens due to the fact that operands of a bitwise operator can be evaluated in any order. Since there are errors for both the operands (invocations of CheckDefinedOperatorArg on arguments 0 and 1), the order in which the error is printed depends on the evaluation order.

  } else if (!CheckDefinedOperatorArg(opName, specific, proc, 0) |
      !CheckDefinedOperatorArg(opName, specific, proc, 1)) {
    return false; // error was reported
  }
