It looks OK to me the way it is. The way I interpret the underlined sentence is "Whatever is inside the <> is parsed like it was double-quoted so that you can do globs on the contents of variables among other things, but you can't do a glob using <$foo> because any time you use a simple scalar inside <>, it's interpreted as a filehandle." The point being, to glob $foo you need to use glob($foo) or <${foo}>.

It says double-quote interpretation "is done first", it doesn't say anything about using literal double-quotes inside angle brackets. But I may be misinterpreting.
