That's an interesting one because, although I've never really thought of it before, I suppose it's technically true (as robinbanks has said, I presume you mean the two ring conductors plus one going to the socket going into a '3-way' Wago)- although I imagine that most people really think of the Wago as being an 'extension of the socket's terminal'.
However, as robinbanks has also said, it doesn't matter, since there is absolutely nothing wrong with a (one) socket being supplied via an 'unfused spur' from a ring.
Kind Regards, John
