The thing is suppose to refer to twins like Kagamines, Anon & Kanon and this pair.

Nemu and Rion are separate characters who actually aren't a duo. Though they have the same provider, Nemu is actually the vocal we're suppose to focus on, and Tone Rion we're not. This is why Nemu appears in Mobile VOCALOID Editor and not Tone Rion. In sort, Nemu is more of a replacement for the older Rion character.

Its complicated, but this is why they've not been referenced here. Whereas with the other 3 pairs of characters their pretty much sold as a duo.
