Well, in theory it seems believable however that really is not totally factual. First off, the pump does not have the ability to "draw" water. It only has the ability to displace it. Because it moves the water, there is a void which is filled by surrounding water in the jackets.
In addition, try this little experiment. Fill a large drinking glass ½ full of clear water and place a straw in one side of the glass. Next fill a pitcher with a mixture of water and food coloring. As someone is gently sucking on the straw, begin pouring the colored water from the pitcher into the glass. Does all of the colored water go directly to the straw, -or does the colored water blend into the entire glass of water?
It is also worth noting that there is a deflector at the inlet that was used on some cylinder cases (engine block) that directed water towards the rear of the case. Also remember there is a cylinder case deck and cylinder head deck with small passages that this water must traverse through before it reaches the water pump.
