That's one of many uses, yes

Presumably the reason you don't have problems is because the partitions
you chainload aren't RAID partitions with 1.1 superblocks, or you're
specifying an explicit offset for your chainloads (Grub syntax allows that.)

Either which way, it's a good example of the usage model.  Chainloading
is important for a lot of people.
