I havn't a clue about what you just posted
Robert, if the post was only for information he would have kept the links as they were e.g.
www.youtube.com/ gd3214896y947r (made up example).
The fact that he changed the title of the link (the anchor text) to "church cleaning" strongly suggests that it was put there as Mike said, to gain backlinks to boost his site. Backlinks, with a keyword included in them, positioned within blocks of text, carry far more weight in the search engines than "raw" ones that begin with www..
Putting them in long boring copy makes them less likely to be noticed.
