Yes. Because it has described precisely the mechanics that accomplish the ends. More analogous to the earlier quoted claim would be: "A surface suitable for temporarily holding the buttocks", which describes both nothing and everything on the earth that is declined more than about 25° from vertical.
I mentioned the engineering in particular because it should be obvious to any engineer that the claim is "vague", because there are many substantially different ways to accomplish it that make a difference that is not comparable to the difference between a wood stool and a metal stool. And because I know engineering, while I don't know or pretend to every detail of the law--I'm only an enthusiast in that area.
If you thought about who your audience is in a thread like this, would you maybe say--instead of "these are specific"-- "these are specific, and here are tests and examples that illustrate that specificity in a patent is different from the normal human usage of that word".
I wouldn't doubt that these are considered specific enough in the current system, but I'd consider that an indication that the system is broken.
