Why did they install the half metal baffle inside the filler neck tube? Does that make it syphon proof and why?

Okay thanks, but how do you know?
If you're referring to the metal baffle with the little hinged flapper just inside the filler neck, no it doesn't stop siphoning . It was added in the mid 70s to prevent putting leaded type motor fuels in vehicles with then new catalytic converter(s). Leaded fuel and catalytic converter(s) were not and probably are still not compatible though I have no idea where you might find leaded type fuel.

The flapper was actually to stop fuel from pouring out during a roll over. It has nothing to do with lead. Lead and unleaded fuel had the same nozzle.
