redirect - Apache 2.4 RewriteRule [R] works but not with [P]

Question

Surly it's only a slight misunderstanding, but I'm stuck with a small problem for days. So I beg for your help

I'm trying to hide small REST-Service behind an Apache2.4 Server

• The redirection works fine: RewriteRule "^/apis/resolver/(.*)" "http://otherhost:10000/$1" [R]

• But with the Flag 'P' the Apache responds with 404. RewriteRule "^/apis/resolver/(.*)" "http://otherhost:10000/$1" [P] Yes, the 'apache' can reach 'otherhost'. :)

Additional Info:

In the error_log I found a hint [rewrite:trace2] ... [perdir /] rewrite 'proxy:http://otherhost:10000/foo/bar' -> '/index.php'

This is related to a part of the confiuration for WP:

<Location "/">
   RewriteRule ^index.php$ - [L]
   RewriteCond %{REQUEST_FILENAME} !-f
   RewriteCond %{REQUEST_FILENAME} !-l
   RewriteCond %{REQUEST_FILENAME} !-d
   RewriteRule . /index.php [L]
</Location>

So I have to redefine my question: "Why is the flag [R] implicit [Last] but [P] not?"
