Apache :: HTAccess For Main Domain Not Affect Subdomanis

I have maindomain.com addon-1.com addon-2.com addon-3.com

The addon domains are folders in main domain's root.

The problem is maindomain's htaccess is affecting the addon domains. I want the add on domains to have their own htaccess. The addon domains should not be influenced by main domain's htaccess

I did some research online and someone says this method works:

Code:

RewriteCond %{HTTP_HOST} ^(www.)?addon_domain.com
RewriteRule .* - [L]

But the above assumes you only have one addon domain. I have multiple.

Which code is correct? This

Code:

RewriteCond %{HTTP_HOST} ^(www.)?addon-1.com
RewriteRule .* - [L]
RewriteCond %{HTTP_HOST} ^(www.)?addon-2.com
RewriteRule .* - [L]
RewriteCond %{HTTP_HOST} ^(www.)?addon-3.com
RewriteRule .* - [L]

Or this

Code:

RewriteCond %{HTTP_HOST} ^(www.)?addon-1.com
RewriteCond %{HTTP_HOST} ^(www.)?addon-2.com
RewriteCond %{HTTP_HOST} ^(www.)?addon-3.com
RewriteRule .* - [L]

do I put the code at the beginning of main domain's htaccess?
