This is of course true, and its a place where the analogy breaks down
slightly -- but no analogy is perfect; they simply serve to help people
view the same problem from a slightly different angle.
The 'suggestion' is flawed in many ways other than this one, just as SPF
is.
An analogy doesn't necessarily help _everyone_ to understand the problem
better, but certainly this one works well enough.
