Since the inner loop declares $i again, it should mask the outer loop's

No, that's not true. You don't redeclare ANYTHING here... you're just using the same variable $i, just like you would do in C.
//In the following example, the inner loop 'i' masks the outer loop 'i':
int array[] = {1, 2, 3, 4, 5};
for (int i = 0; i < 5; i++)
{
int num = array[i];
printf("%d", num);
for (int i = 0; i < 5; i++)
printf("%d", i * num);
}
Otherwise, the declaratory statement in the second loop is completely meaningless.
You don't declare anything...
