Because the way ocp works: first expand anything and when
a primitive not being space/letter/other is found apply the
ocp. This means that fontenc macros are expanded before ocp's
are applied and therefore they become a sort of input method.
In other words, they are being used in a way they were not
intended for. The final conversion from Unicode to the font
encoding is done by an ocp, but one should be aware that
usually LaTeX uses _two_ encodings if properly setup---T1/OT1
for letters and TS1 for symbols. [Unfortunately, many people
don't know this fact and they select T1 withot TS1, thus mixing
two fonts. I think users should not be concerned at all with
encodings, which are not always easy to understand or even
This raises the question of if ocp's are applied at the right
place (which was selected mainly because it was easy to
implement), but that's another story...
