RewriteCond     %{HTTP_HOST}                                (?:.*\.)?([^.]+)\.(?:[^.]+)$
RewriteCond     /home/%1/                                   -d
RewriteRule     ^(.+)                                       %{HTTP_HOST}$1
RewriteRule     (?:.*\.)?([^.]+)\.(?:[^.]+)/media/(.*)$    /home/$1/client/media/$2 [L] 
RewriteRule     (?:.*\.)?([^.]+)\.(?:[^.]+)/(.*)$          /home/$1/www/$2 [L]

Here is rewritelog output:

#(4) RewriteCond: input='tfnoo.mydomain.org' pattern='(?:.*\.)?([^.]+)\.(?:[^.]+)$' [NC] => matched
#(4) RewriteCond: input='/home/mydomain/' pattern='-d'
=> not-matched
#(3) applying pattern '(?:.*\.)?([^.]+)\.(?:[^.]+)/media/(.*)$' to uri 'http://www.mydomain.org/files/images/logo.png'
#(3) applying pattern '(?:.*\.)?([^.]+)\.(?:[^.]+)/(.*)$' to uri 'http://www.mydomain.org/files/images/logo.png'
#(2) rewrite 'http://www.mydomain.org/files/images/logo.png'
-> '/home/mydomain/www/logo.png'

If you note on the 2nd 4 it failed the -d (if directory exists) pattern. Which is correct. mydomain does not have a /home/. Therefore it should never rewrite, atleast according to my understanding that all rewriterules are subject to rewriteconds as logical ANDs.

    No, only the rule that immediately follows one or more RewriteCond directives is included. That is:

                                                              #www.   domain .   tld
RewriteCond     %{HTTP_HOST}                                (?:.*\.)?([^.]+)\.(?:[^.]+)$
RewriteCond     /home/%1/                                   -d
# This will only be run if the two conditions above, are met
RewriteRule     ^(.+)                                       %{HTTP_HOST}$1

# These will always be run!
RewriteRule     (?:.*\.)?([^.]+)\.(?:[^.]+)/media/(.*)$    /home/$1/client/media/$2 [L] 
RewriteRule     (?:.*\.)?([^.]+)\.(?:[^.]+)/(.*)$          /home/$1/www/$2 [L]

    If you notice in your log, it skips the first RewriteRule, but doesn't even check conditions for the other two.
