If you read the article it does make quite a bit of sense especially applied only to cyclists. It doesn't say to do normal stretches immediately before your ride, but to do dynamic stretches (which most of the professional teams are now doing if you've seen the GCN videos on youtube). It also makes sense that cycling would cause more muscle problems because, unlike running, it does cause the muscles to behave in a manner different from their full range of normal motion. Stretching out your muscles before a ride is no doubt a bad idea, but I think we could all benefit from a few dynamic stretches a few times a week by themselves or as a warm up to a gym workout. I'm not an expert by any means, but I have taken a few classes on this type of stuff in college and this seems to be where the expert are heading on these topics.
