it forces HBD conversions to happen sooner after the market turns. In the past HBD conversions only happened substantially after the peak of Hive price - because the price would lag above $1 for some time, and conversions only became profitable only once a substantial amount of Hive was added to the Hive virtual supply in this way.
I think that now, with the price of HBD turning below $1 immediately with Bitcoin, while Hive price still relatively high, it supports this theory. It will only be proven with longer term data though.
