Poliquin says you're wrong:

The Parts of the Pecs
Q: Is there really anything you can do to target certain areas of the pecs like upper and lower? For example, incline bench presses hit the "upper" pecs; dips and declines target the "lower" pecs. Any truth to those old bodybuilding beliefs? abs
A: Actually, there is. Now, you will find some research that says that it's not true, but those studies were done with Radio Shack equipment and aren't reliable.
The truth of the matter is, there's a great percentage of electrical activity in preferential heads of the pectoralis. In other words, the clavicular (upper) portion will be recruited more during inclines, and the sternal (lower) portion will be recruited more during the decline bench press. barbell
But it's a percentage of the contribution; certain exercises don't target one-hundred percent of the lower or upper pecs. So, the clavicular head still works somewhat during decline presses. The percentage of recruitment is merely shifted with certain exercises.
It's the same with biceps. When someone does incline curls, the long head of the biceps is more recruited, but the short head is still working. barbell
Now, with chest work, the further the hands are up in relation to the center of gravity, the more the clavicular pectoralis is recruited. And the further the hands are near the center of gravity, the more the sternal pectoralis is recruited. So, theoretically, dips will recruit more of the sternal pectoralis than the decline press. In that way, you can think of the dip as an extreme decline press. dips
All that said, there's no such thing as the middle or inner chest, so obviously that nonexistent area can't be recruited by flyes or pec deck.
