Someone pitches a loser as the last play at trick 12 so that his trick 13 claim with the high trump will be clear? Is that what you are saying? Even if such a person exists we know it is not the actual declarer because he actually tried to claim before trick 12, so we know he wouldn't have reasoned that way.
In a nutshell, yes. The only way EW will score one of the remaining two tricks is if the TD and/or appeals committee determine that in the absence of the claim it would be careless, but not irrational, for declarer to pitch a loser as the last play at trick 12 so that his trick 13 claim will be with the high trump.
I agree that the vast majority of competent players would indeed ruff the
♦10 and put their "losing"
♣8 on the table on the off chance that they've missed a discard or weren't following the pips properly. To not take that precautionary line in the two-card ending would certainly be careless, but you couldn't call it irrational to be conceding a known losing trick.
The test here is not what you or I or any other competent player would do. Nor is the test what we think this particularly person would do. The test is would it be careless but not irrational to save the trump for trick 13 when you are in a mindset of believing that your other card is a guaranteed loser.
It's distorting the facts somewhat, but when a person truly believes they have an unavoidable loser they could just have easily made a claim statement such as:
"all I've got is the top trump, so one for you and one for me"; or
"my club is a loser, so I'll just take my top trump at the end".
When people have lost track of the pips and don't know what's high or, as in this case, firmly believe that a winner is actually a loser, they have been known to do careless things in the end-game. We have all observed careless plays in end-positions based on misapprehensions of what's high or not and I dare say that very few of us would be entirely innocent of not making such careless plays at some point of our careers.
