Details:

In MATLAB,


>> bitor(-10,20)
Error using bitor
Double inputs must have integer values in the range of ASSUMEDTYPE.
 
>> bitor(-10,-20)
Error using bitor
Double inputs must have integer values in the range of ASSUMEDTYPE.
-verbatim

in GNU Octave,


>> bitor(-10,-20)
ans = 0
>> bitor(-10,20)
ans =  20


So, it's producing error, warning for negative inputs neither the result is
correct.
Most importantly,help bitor says,


 -- bitor (X, Y)
     Return the bitwise OR of non-negative integers X and Y.
...


So, according to the help it should throw error for negative inputs.
