It depends.
When you concatenate the DSNs, for a given DD (say DD1), they are stacked one-after-other in the oreder they are placed in JCL. If the program pointing to the DD1 DD does not bother about how they are concatenated, yes you are correct else you might get an error; for example if a program is written to handle some keys in ascending order but the concatenation distrubs this ascending order, so it won't work.
