Odd behavior of a Single Photon

Is the paragraph correct at the following web page under the heading
"measurement of the wave?"

http://muller.lbl.gov/teaching/Physics10/chapters_Jan_2005/Chapter10.htm

It says,

MEASUREMENT OF THE WAVE
Suppose a very broad wavepacket of a photon hits the CCD (the light
sensitive detector) in a digital camera. You can even assume that the
width of the wavepacket is larger than the entire camera. Because the
packet is so large, does it give a signal in every pixel of the CCD?
No. It knocks an electron out of only one pixel - because it has
only enough energy to affect one.
Which one? Quantum physics supplies a curious answer. The electron
knocked out will be random, but only in the region where the wavepacket
hits. The places where the wavepacket is stronger (greater amplitude)
have a higher probability. In fact, according to the math of quantum
physics, the probability is proportional to the square of the
amplitude.
So quantum mechanics is inherently a random theory. There is no way to
predict where the electron will be knocked out.
Some people like to say that the position of the knocked out electron
represents the "true" position of where the photon "really was." But
that's wrong. The wave is spread out over space, and the photon is not
hidden within this range. We know that because of soap bubble - the
photon can bounce off both the front and the back of the soap bubble,
because it is a wave, not a localized particle.

So a single photon cannot be absorbed by two different CCD pixels? If
we have two detectors-- detector A and B. Say detector A and B are
separated from each other. The above claims that a single photon
cannot knock out an electron from both detector A and B. How certain
is the above assertion? How well tested is this?

Lets say the detectors are well made and a single detector is capable
of absorbing a photon every time, or very close to 100% of the time.
What if detector A is slightly closer to detector B so that detector A
will always see the photon just prior to detector B? Let's say the
time difference is only one pico second; i.e., the photon would
normally hit detector A 1 ps before detector B. So detector A tries to
absorb the photon. Since detector A gets first stab at absorbing the
photon, then does this mean that detector A will always absorb the
photon every time or almost 100% of the time? If not, then what's the
probability?

Many thanks,
