Means that from now on, HIVE - HBD conversion on the posts rewards will reduce linearly if the debt keeps increasing up to 30%, where HBD printing will be halted (everywhere).

I still need to check this comment of mine:

After 30% debt, the only way to get HBD is to convert it from HIVE (with 30%/debt% ratio) or by trading
