This is normal, but you do not understand.

Setup shouldn't uninstall anything unless you tell it to or it is
preparing to upgrade the package.

Default means get everything in the default set, or upgrade it if I've
already got it.

Setup automatically installs dependent packages.  So, if vi depends on
another package, you will get that one too (extra stuff).

Sometimes, but not recommended.

Some have postinstall, preremove, etc. scripts.  See /etc/postinstall,
