When you use only pressure you trap the air in the wood which prevents the solution from making contact with the wood fibers plus the solution may contain air which would also be forced into the wood.

I realize this explanation is far from perfect but it is what has been written in the various knife forums. I hope it helps to explain this a little bit.

Hope this helps,
