The trick words is how to shortly tell this "the snapshot used to start
transaction <n>".

And it's even more trick when we think about commit retaining.

My understand is that if transaction <n> had a commit retaining,
subsequent new derived transactions will use the snapshot after the
commit retaining in <n>.

However, a already established derived transaction from <n> will ignore
subsequent commit retaining done in <n>.
