Bug? Non-Blocking for Minify always Blocks (in Auto mode)

Seems the only way to get non-blocking feature to work (under minify) is make sure you are in Manual mode. In Auto mode regardless if you select Non-Blocking using JS, or any other mode, this plugin always makes the javascript blocking (uses default blocking mode). In Manual mode you see the proper action (e.g. i see the w3tc code use a non-blocking function call to load the javascript).

So, unless i am misunderstanding how this should work it seems the Minify Auto mode has a bug when one decides s/he wants to non-block javascripts in the head (it will always load it in blocking mode).
