Apache treats multiple slashes as a single slash. This affects things such as RewriteRules, e.g. if you have a rule like this:

RewriteRule ^user/(.*)/([0-9]+)$ /user.php?id=$2 [QSA,L]

That will catch links such as user/nomaD/500 but it will not catch user//500 since it treats that as user/500

So in other words, I don't think your setup will work since it will treat param1 as method and shift all the parameters left, unless they are of a specific type. I guess this doesn't affect your specific case, but in a lot of situations, this would be a downside to using //.
