"rewrite the output of this field" doesn't honor theming of "field content"

Edit view Projekt:
page 4:
Fields: field 1 .. field n, one of them: "field_projekt_downloads";
field n with:
X rewrite the output of this field:
contains html-code including the other fields 1..n and: [field_projekt_downloads_fid]
during having an existing (and correct working and done "rescan template files")
views-view-field--Projekt--page-4--field-projekt-downloads-fid.tpl.php

The .php-file does not take any effect, the field "field_projekt_downloads" is displayed normally.
If you don't check "rewrite the output" the php-file works fine.
