Same origin policy in external js file

Question

if the website http://www.mysite.comhas an external js file added as

<script src="http://www.yoursite.com/new.js"></script> 

in the http://www.yoursite.com/new.jsjs file , there is an ajax call to the script inhttp://www.yoursite.com/new.js

in this case there will be a security problem of a policy of the same origin, since it calls a script on a site from another site?
