Hi Vincent, PagedLOD only ever expires high rest children that are nolonger needed. It never expires low res children when viewing a high rest child as you always want the low res child to fallback on when you suddenly move away. The cost of a low res child is very much lower than the high res child (typically a 4:1 ratio) so the cost of keeping it around for when it'll be needed in the future is actually very low.
