In the CR tool I assume it may have looked more like this:

        if ((err = SSLHashSHA1.update(&hashCtx, &serverRandom)) != 0)  
            goto fail;
        if ((err = SSLHashSHA1.update(&hashCtx, &signedParams)) != 0)    
            goto fail;
    -   if ((err = SSLHashSHA1.update(&hashCtx, &somethingElse)) != 0)
            goto fail;  
        if ((err = SSLHashSHA1.final(&hashCtx, &hashOut)) != 0)  
            goto fail;

Which is a little harder to see. Obviously you should always look at it in a side-by-side view (god I wish github would implement this) or at the resulting code, but people are imperfect.
