This is about the Keyshot Bridge and not about Keyshot for ZBrush.
Pixologic is responsible for the Bridge and - as I understand - allows it to be used on 2 computers (provided they are not running at the same time) just like ZBrush itself.
Keyshot (for ZBrush) is the responsibility of Luxion. All products of Luxion are allowed to be used on 1 computer only (unless you activate and de-activate).
In case you own already Keyshot (1 license, 1 computer for example laptop) and ZBrush (2 computers, for example laptop and desktop), I think you could buy the bundle (Bridge + Keyshot for ZB) and install the bridge on both computers and Keyshot on for example the desktop since already on the laptop … just an example. With that in mind that Keyshot for ZBrush only works with ZBrush and not with any other 3D software application.
That’s how I understand it but I might be wrong (wouldn’t be the first time). Since I bought the bundle and am waiting (support ticket) for the license key (I only received a confirmation of purchase, like some others) I asked the question about the above too … just to be sure.
