Yes the patch will mess with the export and descr files.
But I doubt it will mess with anything that is significant in the descr_strat.
Even if it does, there is nothing BIG that it will change in the descr_strat that we couldn't change ourselves.
So for example, justme is the one editing the descr_strat, he will make a back up of the one he is currently working on, then install the second patch, then put his descr_strat back in place... thus overwriting the patched descr_strat.
