C/C++ Compiler generates false positive MISRA warnings

When I enable MISRA rules check for the C/C++ compiler for MSP430 I get the MISRA warning 10.1/R for the following code.

typedef enum _MyEnum { One, Two } MyEnum; 
MyEnum MyVariable; 
 
int foo(void) 
{ 
    int result = 1; 
 
    if (One == MyVariable)  // fails here with MISRA-C:2004 10.1/R 
    { 
        result = 2; 
    }     
    return result; 
} 

Our coding style convention requires that the variable is at the right hand side. Therefore I don't want to swap One and MyVariable, although that makes the warning to disappear.

Is that a bug in the MISRA checker? If not, why is the comparison of two terms not commutable?
