What are you asking when you ask "how". Are you asking "how" can it be 320 to 1280 using the 2x or are you asking "how" can it be that it will autofocus with the 1.4 extender and not autofocus with the 2x extender.
My question to you is are you talking about the Canon 100-400mmL f4.5-5.6 version 1, or the Canon 100-400mmL f4.5-5.6 version 2. Because if you are talking about version 1, the push pull zoom, you don't want that one and it probably won't autofocus with either of the extenders.
100x1.6=160
400x1.6=640
100x1.6x1.4=224
400x1.6x1.4=896
100x1.6x2=320
400x1.6x2=1280
This is the field of view you get with a crop sensor using L series lenses.
