Lol, it's like when you chat with your roommate, even though is computer stands next to you, the signal may go though up to japan, new york and L.A. before it comes back to you
Then, was it because you installed you phpBB in a sub domain and still mentioned path in .htaccess ?

The rule you mention is just checking if a virtual folder would not be injected.
This comes from the way title injection is made possible. Let me explain, in the RegEx, we do not know the topic of forum title so we have to accept any text (restricted here to at least some) before our rewrite anchors (-vt, -vf, -vc ...).
The way I designed the rewriterules forces the use of .html at the end of each URLs as well, let's consider an example :
-www.example.com/forum/topic-title-vtxx.html being the correct URL.
The rule you are talking about is juts making sure that :
-www.example.com/forum/topic/-title-vtxx.html is redirected to the index.
because other wise this URL would still load and break all relative path (href="formu/ ...") as they'd start from the virtual folder "topic/" for the browser in thi case.
This won't be an issue anymore with the zero duplicate mod soon to come.
as we'll be able to play this much (note that this site is using a slightly different URL standard, but the principle will be the exact same) :
http://boards.phpbb-seo.com/the-phpbb-s ... vt126.html
http://boards.phpbb-seo.com/the-phpbb-seo-website-lies-to-you/many-duplicates-are-possible-vt126.html
http://boards.phpbb-seo.com/viewtopic.php?t=126
http://boards.phpbb-seo.com/viewtopic.php?p=908
With pagination handling :
http://boards.phpbb-seo.com/viewtopic.php?p=1238
http://boards.phpbb-seo.com/viewtopic.php?t=4&start=45
As you can see the solution is total and will allow us to moderate topic titles with no SEO harm at all (HTTP 301 is our friend again here

)
