I think that the point is that if it's possible to take a shot quite quickly there must be a lot of light about...
If however there isn't much light about the shutter speed would have to fall and although the exposure could still be the same the look of the two pictures (one taken with a "correct" exposure with quite a bit of light about at a fast shutter speed and the other taken with a "correct" exposure with less light about and a slow shutter speed) may in all probability look slightly different and possibly render noise differently.
Seems pretty reasonable to me, as is the point that in the real world, if we had time, any of us would probable drop the ISO a bit if the shutter speed was in the 1/xxxx range.
