They can access the exact same data also, it would just mean some
delay for one or more of them, and maybe some arbitrary decision about
the sequence.

(But if they use SHARE.EXE on the DOS side, as I understand it to
work, then there will not be concurrent access to the same DOS
files. And then it's a question of the mapping from those to image
file locations.)
