ya its correct.
If you're using Google AdSense with more than one ad layout or on more than one area on your site or even more than one site, you must be using channels to really understand how your site traffic flows and what's really generating the revenue for you.

And by this way one can use his/her adsense account in as many website/blog as he/she wish without applying for adsense account for the second time. Google is providing channels, ad filters and many more facilities along with adsense codes in order to maximise the revenue earning from the point of view of the publishers.
