It just doesn't happen that way and the world is actually round - not flat

Taping the spine is like cutting all the rubber off one spot on a tire so that your car won't roll away when parked.

Actually there seems to be some historical precedent to a lifted spine, even a device to lift the spine to hone true wedges, we are still looking for definite proof but the evidence is a little compelling...
That aside, there is another reason for 1 layer of tape when honing these oldies, imagine a rutted old road (the spine) and every time you try to drive down (hone) the road (the edge) you keep getting pulled into the same old ruts...
Now along comes a road grater (1 layer of tape) and smooths the road (the spine) which now makes it much easier to steer clear of the obstacles in the road....

I never advise more than one layer unless you are doing serious restoration but on these razors it helps get a good even bevel going ...
