On: Wilhelm von Hackensplat: 'First Past the Post' isn't.

If I understand rightly, the AV system being discussed in the UK allows the voter to choose to vote for either one or a limited number of candidates.

All votes won't be carried to the final round so this means the winner isn't guaranteed a 50+% share of the vote.

People don't have to fill in all candidates, so some votes may be lost along the way. The winner is guaranteed a 50% vote share of all votes that make it to the final round - and nobody is denied a chance of getting their vote there.

Its guaranteed that 50% to either prefer the winning candidate to the other electable candidates or have not expressed a preference.

This is very true, but the original point still applies.
