How would it be less effective ? We're talking about point loading here
Steve and Myka pretty much covered what I was pointing out
Point loading the concrete floor will break it
By placing a larger foot of something that won't break under the load, you're spreading the weight out over a larger area, thus putting less stress on a smaller area of the concrete
And ya, the wood he has there under the post will collapse under load
Have you ever hammered any soft wood ? It compresses very easily
His wood will compress and/or split
