Yes, you are wrong.
The Fibonacci sequence can be defined by:
F(1) = 1
F(2) = 1
F(n+2) = F(n+1) + F
The first two parts of this definition are
necessary to the recursion. It cannot work without it. Moreover, there is nothing in the definition that makes one part contradict any other part.
For your definition of Or

, you included
unnecessary components. Worse, those unnecessary component contradict other components. Your definition for Or

is not self-consistent.
For Or(1), your formula devolves to a summation over an empty set and requires no explicit definition for value. The definition for Or(1), therefore, is unnecessary. Worse, the definition doesn't agree with the formula.
Also, the Fibonacci sequence recursion requires two "starting values" because of its formulation. Your recursion for Or

, just by its form, doesn't require two starting values.
To be proper, your starting values for a recursion must be (1)
necessary and (2)
consistent. Yours are neither.
