Only because this error already exists in the POE argument,
thus the same error is transferred to the syllogism when the POE
argument is accurately translated into the syllogism.

It is the exact same invalid syllogism with the non-sequitur
as the POE argument that it was translated from.

(A is True) and (A is False) should have been rejected
by the principle of non-contradiction before the POE
argument was ever evaluated. The only reason that they
were not is the dictatorial fiat of arbitrary convention.
