Yes, that's true. The logic is that if you're only wanting to utilize a form on your website, you shouldn't have to create a landing page first and then drop it on and possibly another landing page after that to act as a confirmation. In reality, this is the better way of thinking, as it lets you split out forms you're embedding from actual landing pages (and the forms on those).
Unfortunately your setup is like most who worked with forms 1.0, which is more or less the exact opposite setup.
Personally, I'm waiting for a major event (e.g. website redesign) before I go through the effort of undoing the old setup for the new.
