Makes perfect sense to me and for exactly the reason you noted in your last paragraph

You need more insurance should your death be “premature”- that is to say, you still have to make arrangements for the care and feeding of minor children, keep the family in the house you’re currently residing in, replacement of your income for the sustainability of the family over time. When none of these factors are in play, your need for life insurance is drastically cut and you weigh the return on investment of payment of premium on term life insurance.
