The swingarm is not floating, it is affixed to a single pivot.
As aforementioned, it is only the shock that is actuated by linkages, presumably to introduce some kind of rising rate action. In essence it is now much lime a typical motorcycle mono-shock system, where the swingarm rotates about a fixed, single pivot and the shock is actuated by top or bottom mounted linkages.
So, yes, this bike is very much single pivot - count them! One, er, one. One. If Orange are suggesting otherwise its very disingenuous of them.
