Except the surprisingly common case that lanes are mislabelled... Ie. "I was in the lane marked M4, I followed that lane round perfectly, and suddenly the label in the lane changed to A205! I better change lanes. Oh actually the lane I was just in is now marked M4 again."
The problem seems to be that a lane that goes to two places is sometimes marked inconsistently with each of the two places - meaning you think you are in the wrong lane, when you are not.

And the good ones have lane markings that guide you to the exit as you go around too

Yeah for sure, otherwise it'd be quite scary! Although there are plenty, particularly where there might be more exits where its pretty easy to mispredict where your lane will end up.
In practice, large multi-lane roundabouts in the UK usually have lane markings as you enter, with specific lanes for each exit. In general, so long as you were in the correct lane as you entered the roundabout, the lane markings should guide you to the correct exit and you shouldn’t have to do any filtering.
