[thelist] SEO keywords not on source but on copy??

[Flavia Tarzwell (FayeC)]

A friend of mine has a client who is concerned about his positioning and 
how his competitor always gets a better positioning than his site.....
So he sent the URL for my friend to look at and something really 
funny/weird came up.....
If you check the source of the page there are only a few keywords in the 
actual meta tag but if you copy the page's content and paste in a normal 
text editor you get some 4 extra pages of keywords after the content 
that's actually showing.....
Can anybody explain this? I had never come across such a thing and my 
friend is curious too so she can implement something to beat the 
competition's positioning....she just asked me if I knew what was that 
about.....
The URL is:

Thanks in advance,
