bug#32850: 27.0.50; window-swap-states doesn't swap window prev/next-buffers

This looks consistent to me.  The respectively "current" buffers have
been swapped and the previous and next buffers of each window remain
the same.

In which sense?

So far I'm missing you.  How would you define consistency in this
context?
