  In a recent paper, [Gampel, F. and Gajda, M., Phys. Rev. A 107, 012420,
(2023)], the authors claimed they are proposing a new model to explain the
existence of classical trajectories in the quantum domain. The idea is based on
simultaneous position and momentum measurements and a "jump Markov process".
Consequently, they have interpreted the emergence of classical trajectories as
sets of detection events. They successfully implemented the model for a free
particle and for one under a harmonic potential. Here, we show that the
continuous observation limit is a realization of a coherent semiclassical
expansion; Also, as has already been demonstrated, the jump process is not
necessary and is not observable. In other words, the collapse, as they propose,
is a non-go theorem; even if it is real, it can not be measured under the
needed assumptions to obtain Newtonian classical dynamics.
