Crossing blown bridges over super rivers

[Cpl GAC]

I've noticed in this scenario pieces can cross super rivers after I have blown the bridge. In this example, the unit has no Ferry ability and a 1% Engineereing ability. He should be stuck, yet crosses with 4mps.

The passing the cursor over the hex reads "movement cost 7, super river, road, bridge destroyed, (observed)". I have new bridge rules set to ON.

Is this a scenario design thing or a problem?

I think I found my answer - it's the 1% Engineering ability;

12.3. major ferry support
Land units cannot usually enter Super River or
Suez Canal locations. Units that have a Major
Ferry Capacity of greater than 10% have the ability
to enter these locations and create temporary
crossing points for other units. If the hex contains
a blown bridge, a unit with engineering equipment
can move into, or through, the hex and even
attempt to make repairs.
