Because the browser is not obligated to provide that information:

 $_FILES['userfile']['type']
    The mime type of the file, if the browser provided this information...

You (the server programmer) can't "tell" the browser what to do. For example, the browser owner/user may have his/her browser set so that it does NOT include/supply the referrer header. You, the server developer/webmaster do not have control over the browser. The browser will do as the browser owner/user wants, not you. For your purposes, what you can do is obtain the name of the image and check its extension.
