/photos path

I have a 301 redirect to direct my old gallery2 install to G3. What I'm noticing in the headers is that it first redirects to the /photos/#, and then to the full path. I'm not sure if this is mixing up Google's indexing as I am seeing entries for /photos for my site, and it's also (logically) complaining about identical content between the /photo and the full path.

Is this by design or did I miss something? My redirect is setup like this under my G2 install:

<IfModule mod_rewrite.c>
  Options +FollowSymLinks
  RewriteEngine On
  RewriteBase /gallery
  RewriteRule ^gallery/(.*)$ /gallery3 [R=301,L]
  RewriteRule ^(.*)$ http://www.mysite.com/gallery3/index.php/g2/map?path=$1   [QSA,L,R=301]
</IfModule>
