The important part of what you're saying (if I understand correctly) is that the stride length is exactly 1/2 of the full cycle length.
In A:M parlance, yes. It is the distance from, say, a left footprint to a right footprint, which is half of a walk cycle. (A full cycle would be left to right to left)
It may be that is an ambiguous term. In looking up definitions of the noun "stride" I find that it may be intended as one step (in humans) or as the complete cycle of motion (in horses).
