Eh?

Observed on BBO at one point over the weekend, while trying to escape from Olympiad marking. In what had, to that point, appeared to be a top level teams match, declarer holding QT5 opposite dummy's K743 in a side suit, with the hand well under control, and the ace almost surely on his left, but no endplay imminent, chose to begin by leading the queen.

I still don't get it. Dummy entries were short, so it was infeasible to cross and lead towards the ten, but it would still seem to make sense to simply lead low from hand to the king, no?
