It does, because we’re talking about the total lifespan instead of remaining lifespan. A person who is 120 may have a 10% chance of living another year; but a 50 year old probably has less than a 1% chance living 71 more years. Of course the 50 year old probably has more than a 99% chance of living another year. So the older you are, the older your expected total lifespan is, even if your expected remaining lifetime is shorter.
It’s just really hard to talk about expected lifetimes and not sound that way.
