Yes they have had those two pictures reversed for ages
However, if you open the section on Green Filters it says :-
"Green Filter 061 (13)
This filter differs from the above yellow-green filter primarily because of its increased red attenuation. A red roof or red flowers will become even darker, as will red lips and a dark tan and, unfortunately, so will skin blemishes. This filter is ideal for nature photography. In object photography, it is good for darker reds and lighter greens. Its filter factor is appr. 3."
Then if you open the section on dark yellow it says :-
"Dark Yellow Filter 023 (15)
The even greater blue suppression and the attenuation into the blue-green range leads to a further increase in the effects described above. Interesting for snow scenes under a blue sky, because the darkened blue shadows in the snow make the shapes of the landscape look more dimensional. Freckles and skin blemishes are diminished strongly, but lips are rendered more pale (to compensate for you may use a dark lipstick!). Its filter factor is approximately 3."
