The installer files are automatically deleted when the installation finishes.

That is how a Recovery installation works, since the Recovery system was introduced in OS X 10.7 Lion. The install files never go to a Downloads or Applications folder, because your user account(s) is not used in Recovery.

Why would you want to have two internal drives, each bootable with the same version of the same OS? If you're concerned about being able to boot the system in the case of a disk failure, that's what the Recovery system is for. https://support.apple.com/HT201314

However, if you're intent on doing that... The method I'd suggest would be to boot into Recovery and then "Reinstall macOS." You'll be asked which drive you wish to install it on.

Then which os better to install on second hdd ?

There is no "better." This is purely a matter of what you need. If you don't need to use a second OS, then there is no need at all to install a second copy of the same OS - just use the second HDD for storage.

Software developers often need to test their work on several different OSes.

Some people need to use Windows as well as macOS.

Some people have old applications that won't run on the current macOS and so have both a current version of macOS and an older one.

If none of those situations are true for you, then you probably don't need a second OS installation.
