It means po the same ng objective the difference is redistributed is pushing all connected routes.

yes,

what it means, lahat na na-collect mong routes sa bgp mo, ay i-redistribute ng router mo sa ibang participating routers.

example, may router ka na naka-bgp sa upstream mo at naka-collect sya ng 800k routes, and then meron ka ring IGP sa network mo, you can redistribute those 800k routes sa ibang router mo.
