I guess the graphing code tries to simplify the equation you throw at it. I haven't actually checked the code, but it wouldn't surprise me ... after all, the equation needs to be evaluated numerically over and over, for different values of X, so simplifying it might give it a nice performance boost if the equation is needlessly complex. Then the flag -119 thing would be nothing more than a side effect of re-using the existing simplification routines in CAS.
