I think you'd normally include a comma before "on all" then. I'm not convinced that's what the author meant, but at least it makes more sense than what I read it as. Thanks for guiding me through that.
There's more discussion about it on the WAN show https://www.youtube.com/live/tkYiqvA7pmU around 33:42. They're competent people, so if some interpretation doesn't make sense, maybe it's not a good interpretation.
