Apparent OR re Through end

This paragraph is discussion added by an editor, possibly OR and not encyclopedic format, a YouTube video is the source given:

There are problems with the example illustrated by this page and simplifications implied. Isterdalen (illustrated) is an example of a glacial trough which exhibits a large step (downwards) in its long profile, but, as can be seen in one of the pictures, it is a U-shaped valley up-stream of this point as well. A better example is the Loch Avon basin of the Cairngorms in Scotland which starts at a trough-end, and the land up-stream shows little or no modification by glacial processes. <ref>Archived at [https://ghostarchive.org/varchive/youtube/20211205/1WLE0KRK4WM Ghostarchive]{{cbignore}} and the [https://web.archive.org/web/20201222032642/https://www.youtube.com/watch?v=1WLE0KRK4WM&gl=US&hl=en Wayback Machine]{{cbignore}}: {{cite web| url = https://www.youtube.com/watch?v=1WLE0KRK4WM| title = Cairngorms Loch Avon Basin in May (UHD 4K) | website=[[YouTube]]}}{{cbignore}}</ref> The simplification implied, that glacial troughs generally start at trough-ends, is not borne out in mountain ranges (such as Norway and Scotland) where many glacial troughs are through-valleys, where the glacial trough draining away from the water-shed is connected to the glacial trough draining in the opposite direction, with little or no high ground separating them. These two problems merit a re-wording of this entry, choosing a different exemplar and referring also to through-valleys as found in Norway and Scotland.

Yes, this is not appropriate is it? But the point raised by the editor (apparently in error in the article not here) looks a valid one. User:Curamach care to expand your point, or better, just boldly make the changes? DanHobley (talk) 14:56, 10 January 2022 (UTC)
