The interest is to characterize a relatively sudden phenomenon of excess mortality, not necessarily to compare them.
But indeed they compare, but also introduce a "standardization", which allows to take into account the evolution of demography in number on the one hand and in age on the other hand. According to their estimates, the same heatwave in 2003 would have killed 23700 instead of 15300 if the 2003 population had been that of 2020.
Personally, it seemed very educational to me.
