That's not a "redirect" in the sense that velocio is talking about - that's just a straight link to another page on a website with no redirection going on. The redirects that are affected with the dropping-anchors problem are true redirects, those that involve a 3xx HTTP status code. The redirect happens on the server, in the background, after you've requested the original resource. So that's why it's handled differently on timetriallingforum.
(I don't know why NLFGSS uses 3xx redirects in this way but there's presumably a purposeful architectural reason for that)
I did notice that Old LFGSS links all redirect correctly to their new URLS so figured that the redirection could be an artifact of that - allowing everything to keep its old pagerank. Thought of that while I was in the bath 20 minutes ago, just like Socrates in that film that time.
