Here is a doctored version of one of the pics.
I made one like you are asking about and did not like the results. There was more pops and cracks coming from the handle area and the occasional muffled smack of wood when the bow was released. When the bow is strung and being drawn, there is alot of pressure in the handle side. The blue area offers a bigger chunk of wood of "free" wood to handle the pressure. Also, if the handle is fixed to the other half of the bow, the angle of the cut will act like a ramp ( red arrow) and it would be easier for the handle to slip some and possibly come out of the sleeve. That is not a good thing when the bow is at full draw. You can look at it like this, with the handle fixed like in the build along, when the bow is being drawn, the cut in the wood is being pushed together, if the handle is fixed to the other side the cut in the wood is being pulled apart. I hope this helps.
