I think he got it well enough, it's just not his truth.
Like if Watts says, "Life isn't a journey, it's a dance," one can hear that and say, "Ok, I get what you're going for, I've reflected on it deeply, but for me, life is a journey, not a dance." And it's not necessarily true that, if one reflects deeper, and grows wiser, and puts down one's preconceptions, etc etc, they will eventually, in the fullness of time, realize Alan was right. That's the sort of presumptive condescension that is being called out.
