How Do Waterproof Matches Work?

I know that water extinguishes a flame due to water  removing energy from the system, preventing the reaction to go over the activation energy. I don't get how the wax on fireproof matches work. You need  fuel, oxygen  and heat for combustion but I don't see the wax helping any of these 3 factors in water.

Waterproof matches wont keep the match lit underwater. The wax coating just prevents the wood and chemical head from absorbing water. Once struck you will need to keep water away from the burning portion or they will go out.
