Your example script not the cfengine way of thinking. All conditional 
actions are determined by defined or undefined classes and not by 
if/else statements.

What you probably want is the singlecopy option:

control:
 singlecopy = ( on )

copy:
 /distdir/${host}/passwd  dest=/etc/passwd server=...
 /distdir/all/passwd  dest=/etc/passwd server=...

(This is extensively copied from the cfengine reference manual, I 
recommend having a look at the the singlecopy-option in there).
