USB License vs Soft-eLicense

What’s really the difference between the USB donlge and getting an activation code online? Can I use one activation code on one USB license but on different computers using the dongle? I would like to have Cubase on both my desktop and laptop for convenience without buying it again. Is this possible using the USB dongle?

Soft e-license is tied to ONE computer.
USB e-license is tied to ONE dongle.

The dongle can be removed from one computer and attached to another.
In this way, Cubase can be used on more than one computer (but not at the same time).
