Sounds reasonable to me.
In fact I also came across the first cut-offs over the weekend, an example
is . But I found it rather difficult to decide for one state or the
other. According to  (page 2) the border does not necessarily change if
the river does: "The creation of a new channel after 1850 by sudden
avulsion will not alter the location of the state border. [...] The rule of
gradual and imperceptible erosion and accretion will apply." So I let
Victoria win there, even though I don't have any data from 1850
