Thanks for the details -- I knew it was something like that. In any case, he clearly could've expressed the issue better. But what he did was entirely reasonable -- whereas there is a fair case to be made that voting for cloture, and against a bill, is somewhat hypocritical.

I disagree with that case. I think there are times when you can, in good faith, say, "I am not sufficiently satisfied with this bill to stand in active support of it, but neither do I feel it is sufficiently bad to warrant taking even extreme action to block it, and I recognize that a large majority of the American people wants us to take some action, so I am not going to stand in the way of an up-or-down vote." But I get how you could be on the other side. (Though I find it rather amusing that Republicans, after bitching about rare Democratic filibuster in 2002-2006, have now discovered that it's noble to resist up-or-down votes.)
