Missing security updates

[macmacmacr]

When I check the installed security updates through "system information" on Yosemite.
Security update 2015-001
Security update 2015-002
Security update 2015-004
Security update 2015-006
Security update 2016-001
Security update 2016-002
Security update 2016-003
Security update 2016-004
Security update 2016-005

The missing updates Security update 2015-003 and 2015-005 are missing. I have tried to install manual but get an error can't install which I believe is because it is designed to install on a pre version of 10.10.5. But the problem is that specific update has not been installed. Is their any way to install ? Can i confirm its security patch is installed?

I will be reinstalling my operating system if no resolution as this appears to be a hack designed to omit existing security updates.

You can clean install 10.10.5 and then Security update 2016-005 and won't see any of the interim security updates. The net result is the same: you end up with a fully patched build of Yosemite. Apple's security updates are not required to be installed in order.
Unfortunately, Apple's documentation doesn't make this clear.

They are indeed cumulative.
