My guess as to the combustion reaction is that adding steam increases the oxidation of the fuel, reducing HC and CO output. Best guess, since that effect has been observed in other reactions.
If combustion is performed almost completely in the combustion chamber rather than completing in the manifold and catalytic converter, perhaps that would explain a cooler tailpipe. Don't have any better guesses than that.
