In part because the composition of the commons changes over time - so if the term timescales are different then they won't necessarily agree at any point in time - but I do agree it would potentially become too politicised if you had that kind of vote.
Ultimately in the UK system, the commons has the final say ( ignoring the monarch in the room here ), so most of the time what the Lords do isn't typically a big public issue - it's quiet revision, have you thought of this?, type stuff. Not that common to have a big conflict - though it does happen.
