Subject: Times of Haplogroup "Divergence" vs. Population "Divergence"?

In a recent paper on the European "I" haplogroup and its subclades,
estimates were made of "divergence times" for various pairs of the subclades
and "divergence times" for the populations of the subclades.
Could some one explain in words which are solid but not so professional what
is meant for the divergence time of a subclade's population? A hint is
present in the paper because "expansion" is used interchangeably at one
point. One can imagine a subclade coming into existence in some small tribe
somewhere; the population of the subclade remains modest for thousands of
years, and then for some reason there is an explosion of territory and
population of that subclade at this later time. How is the divergence or
expansion time of a subclade's population estimated?
I think I roughly understand how the time since origin of the subclade is
estimated, but no harm would be done if the person who answers this query
also gives the explanation in basic terms for this divergence time, also.
