I'm pretty sure that this is the fault of the person who wrote the article.
David Burr is not an idiot, whatever else he may be....

I'm pretty sure that what he was actually saying was that around the time
of an eye movement, your perception of the _relative_ locations of objects
is distorted.  E.g. that under certain circumstances you might perceive an
object that is actually to the left of another to be to it's right.  I'd
guess that it's a very small effect (i.e. that the two things have to lie
close to a single line of sight) that only pertains for a small fraction of
a second, which is why no-one's noticed it before...
