Do ADO policies do compression again?

I have a compressed table with ADO policy for 3 months of no modification, but the company management want to change to 1 month. Data already compressed and meeting new policy requirements, will it be compressed again?
EX:
--Old policy
ALTER TABLE TAB_HR 
 ILM ADD POLICY ROW STORE COMPRESS ADVANCED SEGMENT
 AFTER 3 MONTHS OF NO MODIFICATION;

--New policy after old policy has been executed
ALTER TABLE TAB_HR 
 ILM ADD POLICY ROW STORE COMPRESS ADVANCED SEGMENT
 AFTER 1 MONTHS OF NO MODIFICATION;

Edited for better clarification.
