Because there is no syntax error. The statement simply asks if the
character "i" appears in any of your case comparisons. This is why the
[A-H] condition failed, but the [A-K] condition succeeded (as i is in the
range A-K).

Both sytax are correct, they only mean different values when parsed by
bash.
