That's a very good point. Beginners rarely claim at all, and practically never before drawing trumps and being down to all top tricks. I can't think of the last time a novice claimed on a cross-ruff.
We cannot conclude from the evidence of one good play that the player is good, nor from one appalling bad play that a player is a novice. The player is clearly of some experience because they claimed. But there are experienced players, who are nonetheless rather lacking in skill, players who never grew beyond some very basic competences. So they do a few competent things, and a lot of nonsense. They can usually establish suits, cross-ruff, preserve entries, make an avoidance play. They claim when they think they have top tricks. But what they don't do is go off piste. The idea of drawing trumps when you have fewer than the opposition is probably alien to them, as that is just not a technique they know, and they are not reliably in possession of the thinking skills even to consider such an action - conceding trump control to the opposition, in a slam, not even worth thinking about.
The whole (intelligent) point of the play of ruffing rather than cashing the A on the first trick depends upon the recognition that one may have to lose the lead at a future point (and other things besides). Yet this player immediately claimed the rest of the tricks, so actually had no recognition of the possibility of losing the lead on this hand. So he did not do it for the intelligent reason. But there is an unintelligent reason for the action on the first trick too. He was going to ruff that heart at some point so he may as well do it now, and by doing it immediately he can claim because now he has 12 "top" cards for the remaining 12 tricks (4S, 1H, 4D, 3C) without having to explain about ruffs in the claim statement.
The unsatisfactoriness of incompetent claims is that it conceals what incompetences may have occurred once the player discovers that the state of the world as they conceived it does not in fact exist. This player has already made two egregiously incompetent actions in this hand. To the extent a "normal" line consistent with such levels of incompetence can be exhibited where the player goes down, there are legal grounds for adjudicating the player as going down.
