If in fact it's still very likely you can get severe Covid while wearing a mask, then sending the message that "wearing a mask will almost certainly prevent severe Covid" will likely lead people to engage in riskier situations with their masks. For instance, it could be that going to a nightclub while wearing a mask is still pretty risky. Telling people that wearing a mask eliminates risk would likely send more mask-wearing people to said nightclubs. Of course, if wearing a mask was in fact extremely effective at stopping severe Covid, then one could make the argument that it's now worth doing these higher risk activities.
