Yes, that is correct. There is a holder on each side of the cargo area that goes in back of the rear seat where you place the roll. There at the cargo door there is a hook on each side into which the roll connects in the slot that is part of the roll. This is not a hard-shell cover so it is not designed to place anything on top of. You can also take it out of the holder so that it is not in the way if you want unobstructed space. I have been very happy with the cover I purchased from eBay and it has done an adequate job for me.
I had tried to purchase a hard-shell with no luck; it is like the one that comes in the one model that comes with a cargo cover. If you know someone in India, here is another option
Hardshell Cargo Cover . Unfortunately, they do not ship out of the country.
Please let me know if you have other questions.
