Confused about Bogoliubov transformation

So I was told by my teacher today that I am doing the bogoliubov transformation wrong because I'm supposed to have 4 different vectors,

i.e

Instead of Ak and Bk

A1k
A2k

and
B1k
B2k

I'm wondering how this makes sense. I've seen papers with 2 different vectors and their complex counterparts but never 4 different vectors. Any help would be great.

Maybe you can give us the expressions you obtained for A and B.
