It is yeah, but when Mila attempts the OH (which the spear you mentioned) it puts her in a "crouching" state rather than a ground state, so it's suppose to trigger the down throw rather than the ground throw (majority of cases).
@Goarmagon When Mila goes for the wake up OH it's suppose to commence Leon's 2T, not the ground throw. You can only get Hi-Counter properties is if they hold (which they can't when grounded) or from an OH (which commences Leon's 2T instead).
