Multivendor code inside PROFESSIONAL?

{if $smarty.const.PRODUCT_TYPE == "MULTIVENDOR"<br />
<br />
 elseif (PRODUCT_TYPE == 'PROFESSIONAL' || PRODUCT_TYPE == 'COMMUNITY') {
```<br />
<br />
Searching through templates in last realease i have found many code blocks with the above if statements that makes the code more difficult to understand.<br />
<br />
Is this code for multivendor edition and now that is seperated will be clean up?
