It's a leftover/backware compatibility thing.
Before the reflection block was introduced, there was no way to know if 
any metallic modifier was intended for phong, specular or reflection. 
Also, the actual order was totally ignored.

Thus
metallic
phong 1
phong_size 150
reflection 0.8

phong 1
metallic
phong_size 150
reflection 0.8

phong 1
reflection 0.8
metallic
phong_size 150

phong_size 150
metallic
reflection 0.8
phong 1

and

phong 1
phong_size 150
reflection 0.8
metallic

would gives the same result.
This is what I mean by "borrow".
