Traditionally, if a person got married to a woman with children from a previous marriage, he was expected to take care of the children. In this way the interests of the children was at the forefront of this kind of marriage and could even derail or prohibit the process. This was a proverb used to express this responsibility as our elders observes that anytime you pull a fallen branch, the leaves are a natural accompaniment.

As mentioned above, the proverb is most commonly used to advise someone who is about to marry someone who already has children, that they will also look after the children.
