[docs] [issue28976] incorrect description that dose not conform to the actual behavior

[woo yoo]

New submission from woo yoo:

The paragraph that describes the precedence of semicolon encounters a minor error, which said :
"Also note that the semicolon binds tighter than the colon in this context, so that in the following example, either all or none of the print() calls are executed:
if x < y < z: print(x); print(y); print(z)" 
However,the series of print function calls could execute partly if the previous ones are legal.
