The whole NEW/MOD behavior is incredibly complex when you factor in the different behaviors for sequential versus partitioned datasets. I fear this is going to start a whole "I hate JCL" digression, but MOD means very different things for PDS versus sequential. MOD is "permissive" for sequential datasets (it might exist and it might not -- whatever) whereas MOD for PDS members means "must be a unique member name."
I came somewhat late to this, but the basic way to check is to inspect JFCBIND2 for JFCMOD. I use it to test in a program that modified a PDS (clears entire PDS directory; obviated by STOW I).
