i am not sure I understand the question but I will give it a try -- many trees if not most form next years buds this year.  Those buds become the growing points for next seasons leaves and stem growth.  Generally the apical bud does the growing and side buds are in reserve if the apical bud is lost do to damage.  This is true for many herbaceous perennials too.

Trees for the most part have a limited time frame to grow new leaves and once that period is done the plants do not produce new leaves the rest of the year-this is not always true but as principle it is correct any new leaves are produced at the growing points and other areas of the branches do not grow new leaves.

so It could be correctly stated that this years growth will limit the number of leaves produced next year.
