I suspect (though look forward to being suitably chastised if not!) that HS isn't talking about cueing in the sense that you mean here - though having been there I don't really agree with the more general criticism he's making.

The start of the scherzo is cited as an example because a) it's tricky and b) it was a bit scrappy momentarily. Out of nowhere, strings have to play a fast rhythmic articulate motif en-masse in a sort of rhythmic ricochet with the horns, all of it quietly. That's inherently testing, particularly so in the RAH acoustic with its delays and echos. If the conductor doesn't give a couple of beats with the kind of crystal clarity Petrenko was deploying for the NYO on Saturday, well, I'm glad it's not me trying to figure out instantly exactly what speed we're all supposed to be going at.
