Unlike Harry, Hermione has no past link to Voldemort. And, if you're unaware of how Horcruxes work, it would seem much more likely that Voldemort's spirit is possessing some one person, rather than two.
True, Hermione doesn't have a link to Voldemort.
I am aware of how horcruxes work and V had eight in canon (although only one was another human - the only example of such a horcrux that we have. There is no mention anywhere whether it's impossible to horcrux two humans). I tried to leave the possibility open that V and Harry's connection is something other than a horcrux, although my wording wasn't as clear as it could have been.
I like the Bellatrix possession idea a bit better than my own, but I don't think we've hit on Lucius' reason yet.
