Build Websites with Hugo: .ByDate.Reverse not working?

On page 66 of “Build Websites with Hugo” the .ByDate.Reverse doesn’t seem to have any impact on the project page. I download the source code and added the change but nothing happens.
e.g.
{{ range first 1 (where .Site.RegularPages “Type” “in” “projects”).ByDate.Reverse }}

Is this unique to me?
