No, this isn't how it works.It should not be "active at all times".
The reason fast movement blurs a bit in you vision is because of the time it takes for the light receptors in your eye to change what they send your brain.
That means that you will always get that slight blurring effect no matter what! Including when playing games!
There's a reason video recordings have to be set to a certain shutter angle to get a particular amount of motion blur. That's simply because TVs and monitors cannot create motion blur the way actual, physical motion does. No matter how high the frame rate of your monitor gets, it will never, ever produce motion blur on its own. In fact, a 60 FPS video with a shutter angle that's the equivalent 1/240 of a second will look completely unnatural. There will be hardly any motion blur at all! In fact, it'll look a lot like what video games without per-object motion blur look like today.
I am no physicist, so I can't tell you the physics behind why physical movement produces motion blur and TVs do not, but it is a thing and it is real. My hypothesis is that TVs merely emit light through tiny colored dots, whereas the phenomena that produces motion blur requires reflection of light across a surface, hence an object moving quickly reflects light into our eyes in a smooth stream, whereas emitted light does not because it actually a bunch of tiny colored dots changing their color very rapidly.
Look for videos shot at a low shutter angle and then compare them to videos shot at a standard shutter angle (re: any normal movie trailer). The difference should be obvious and immediate.
