Getting my user timeline when using 'GET statuses/user_timeline' with 'screen_name' param value as another user's user_id


Whenever I go a ‘GET statuses/user_timeline’ with the ‘screen_name’ parameter (im not using the ‘user_id’ param) and use the value ‘The Colbert Report’ for example, I get back MY logged in user’s user_timeline. It appears to be whenever I use another user’s user_id value for the screen_name, I get my own user_timeline back. Has anyone else saw this? Is this an issue in the API?
