A general comment here that might help in understanding.

"Redistribution" is a Cisco term that is rather awkward, but has been
adopted by the industry. There are less ambiguous terms I'll mention
in a minute.

But I like to explain what "redistribute" means by expanding the grammar:

      router foo
      redistribute bar default-metric x
      distribute-list y in

means

      redistribute bar information, with filters y and foo metric x, into foo.

The more general terms are import and export. Redistribution is importing:

      import bar into foo [optional filters and actions]

Export is like a distribute-list out.
