It does not. Why do you expect it to?

Apply brain and/or sanity checks before applying automatically generated
BGP filters to your router(s). Roll back if that fails.
BGP prefix filters typically get applied to customer sessions to prevent a
customer from claiming successfully that they route default or other
routes that definitely don't belong to them (often in the expectation that
the customer may be inexperienced and will make many funny errors).
Applying prefix filters to uplink sessions is unusual. Applying them
to sessions you take default from is useless.
