The reason why you are getting the value of j as 4 is because ....in the following line :
you used an Conditional OR Operator ..this operator exhibit "short-circuiting" behavior, which means that the second operand is evaluated only if needed. In this case the first condition is i< 10 which is true ...so it won't check the second operand.....and that's the reason why you are getting the value of j as 4....
