Not true, in the first instance the object has a red pigment and in the
second, white.

Try the following

plane{	-z,0
  pigment{White}
  finish{ reflection Red } }
sphere{
  <3,0,-3>,1
  pigment{Blue+Green} }

White plane, no reflection of the sphere because the plane reflects none
of the primaries in the sphere's pigment.

Cheers, PoD.
