I suspect that when it appears as a 'new package', it's a new kernel and will have a new entry in grub. That's usually when the kernel minor version is bumped. Or when one installs a kernel from backports, testing, or unstable.
But security updates do not count as new pkgs. Thus the kernel is merely 'replaced'. In fact, the previous updates (1-5) are no longer cached and I can't reinstall them.
In the case of stock Jessie, the kernel pkg is (pretty much) linux-image-3.16.0-4-amd64; that part does not change for security updates.
