Infrared tree reflection

This was taken recently at a local park. I Shot the top image using a Nikon D70 with an infrared filter supplied from lifepixel. The camera can only shoot infrared,but it does a good job with infrared.The bottom image was taken with a Nikon D200 and a color infrared filter from the same company. It is called false color infrared and to be honest I am not sure why the color reproduces as it does.
