This is just a guess:
it might make sense in case you have a JTAG interface that runs with
continuous clock - in that case, you have to be in a stable state after
a state move, so that the interface can stay in that state by setting an
appropriate TMS value.
I don't know if such an interface exists and if this was the idea behind
that check.
