single 3-way switch controlling light fixture on knob & tube circuit?

[M Kehoe]

I have replaced all the K&T wiring in my house, except for two circuits, which I'm working on now. I am perplexed by this one light fixture, which is controlled by a three-way switch. There is no other 3-way switch attached to this light that I can find, and I have lived in the house 13 yrs. Why is the light wired this way? Thanks.
