Is it me not understanding cocci grammar again?

Given these input and cocci script files:

Why isn't the show_test1 function transformed?
Why is only the show_test2 function transformed?

The only difference between the files is some
commented out lines with a for loop and if test.

$ cat test.c
static ssize_t test1_show(struct device *d,
		struct device_attribute *a,
		char *buffer)
{
	ssize_t rc = 0;

	for (cnt = 0; cnt < s_attr->size; cnt++) {
		if (cnt && !(cnt % 16)) {
			if (PAGE_SIZE - rc)
				buffer[rc++] = '\n';
		}

		rc += scnprintf(buffer + rc, PAGE_SIZE - rc, "%02x ",
				((unsigned char *)s_attr->data)[cnt]);
	}
	return rc;
}

static ssize_t test2_show(struct device *d,
		struct device_attribute *a,
		char *buffer)
{
	ssize_t rc = 0;

//	for (cnt = 0; cnt < s_attr->size; cnt++) {
//		if (cnt && !(cnt % 16)) {
			if (PAGE_SIZE - rc)
				buffer[rc++] = '\n';
//		}
		rc += scnprintf(buffer + rc, PAGE_SIZE - rc, "%02x ",
				((unsigned char *)s_attr->data)[cnt]);
//	}
	return rc;
}
