Clarification on my part when I look

Clarification on my part when I look at the db-config-sample-256.php example within the multi-db plug-in, I see that on line 298 and down, it reads

//---VIP Blogs------------------------------------------------------------//
//------------------------------------------------------------------------//
// Usage: add_vip_blog(BLOG_ID, DS)
// EX: add_vip_blog(1, 'vip1');

add_vip_blog(1, 'vip1');
?>
On this URL, below, it has instructions this within the optional 6: To add a blog/site to your VIP database simply follow the example given at the very bottom of the file. To add your blog ID of ’1? to the vip1 database just enter.

The question I'm asking is within the multi-db plug-in and within db-config-sample-256.php example, what the instructions are telling you what to do, and what the code reads, it has done this already for you within the db-config-sample-256.php example, correct?
