It depends on what screw will control the bottom end hit on your headpipe. For instance, the SXR wetpipe top screw will move the power band lower in the throttle range. People will take the water from the head and put it to the top fitting then the bottom fitting to T to the stinger and overboard. The theory behind this is that the water is cooler going into the head pipe and cool the exhaust better giving you better hit. From what I have read, the top bottom screw can add bottom end hit on certain applications. You need to play with the water screws to find out what does what on your specific application.

The real question is how much does this have an effect?

Both routes will work, only difference is your water going to the sticker is coming from the head pipe outlet vs the head. Nothing really different than what you have posted. 5150 is talking about intering water either at the top of the pipe vs the bottom. You can run them both. FPP shows it coming into the top of the pipe and coming out the bottom. There is no "right" way. Different builders will plumb the pipes different ways.
Some people run split cooling. One line just for the pipe, and the other for the cylinder.
