That is actually pretty interesting. But I think it has a lot to do with what type of cardio you are doing. First, most people will not be able to do two sessions a day. So it`s either cardio prior to after weights.
A low intensity cardio of moderate duration effort can surely be done prior to a lifting session whithout any detriment in performance.
However anything of high intensity or long duration will durely negatively impact the quality of the workout, especially if it is a lower body session.
So while the activation of certain pathways is nice and well, if you have a bad strength session you are not in a good situation.
