I read 5bellies' post as questioning how an antenna set for left or right handed polarisation without a means to switch, could receive both polarisation signals.
The answer is that it would depend on which services the veiwer was entitled/intended to receive, I think the plan was that viewers in the UK would have one polarisation antenna whilst viewers in maybe Ireland would have the other, so there would be "no need" to be able to receive both.

Edit: In light of Nano's post below, I should clarify that I am referring solely to circular polarisations, as when using a BSB antenna for its original intended purpose

nope you had to physically move the dish 90 degrees

In its normal position you could only get the verticals. To get the horizontals you had to mve it round 90 degrees.

You also had to take into account the frequency shift aswell
