WOW, what a clear comparison.
This is based on 18 USC 1924(a). Comey based his decision on 18 USC 793(f).
A clumsy parallel may be useful. If 793(f) is murder, 1924(a) is manslaughter. When the facts don't add up to murder, that does not mean the person did not commit manslaughter. Comey never applied the facts in the Clinton case, to 18 USC 1924(a).
