Well it's certainly possible to re-arrange it

Try the following 

   
 when HTTP_REQUEST { 
    if { (![string tolower [HTTP::header Referer]] contains ".domain1.com") and (![string tolower [HTTP::header Referer]] contains ".domain2.com") } { 
    if { [matchclass [string tolower [HTTP::path]] contains $::restricted_URL_datagroup] ) } { 
    HTTP::respond 404 content ""  
    } 
    } 
   }

or 

   
   when HTTP_REQUEST { 
   switch -global  [string tolower [HTTP::header Referer]] { 
   "*.domain1.com" - 
   "*.domain2.com" {  
   if { [matchclass [string tolower [HTTP::path]] contains $::restricted_URL_datagroup] ) } { 
    HTTP::respond 404 content ""  
    } 
    } 
   } 
  }

Note: I didn't check the syntax so you might need to tweek it.
