In Scythe, when a mech carries workers across a river, can the workers disembark alone and stay on the opposite riverbank?

In *Scythe*: if I have already unlocked the mech's "Riverwalk" ability, my mech carries 2 workers across a river to reach the opposite bank hex. During resolution of the Move action, can the workers disembark and stay on that hex, while the mech continues with its second step to go elsewhere?
