Yes, that, plus the built-in volume management, plus the simplicity, plus some of the advanced features, are the benefits of ASM. Most of those benefits go away when you're using NAS, so I typically don't encourage people to use ASM over NAS, unless you have to (i.e. Standard Edition).

Otherwise, ASM just adds a black box on top of regular filesystem access - you're locked into Oracle tools for backup and recovery, you probably can't use any of the storage vendor provided capabilities without all kinds of gyrations, and you generally lose all the advantages of the NAS platform.

ASM makes sense as a means of getting around the dumb limitations a lot of enterprise storage arrays have, and as a marketing mechanism by Oracle to convince customers to buy dumber, cheaper storage arrays, leaving more money to spare for licensing. When you have a "smart" storage array, like a NAS device, why add complexity?
