I don't think this was ever answered so here are my reasons.

I think it is very important for both halves of the prop and spar assembly to have the same strength and flexibility. By doing the spar to blade assembly before the spar halves are joined it is easier to match the spars and glue them to the blades in exactly the same position and with exactly the same orientation of the grain in the spars relative to the blades. Once that is done you can join the halves by whatever means you prefer. My F1L props have a small center hub of balsa with the prop spars glued to the front of it. For A6 my spars overlap at the center as Kang described. For LPP my carbon rod hub is done as one assembly but that's a special case.
