No, this happens when a segment below the graft point (which is a completely different citrus) is allowed to grow and overtake top graft branch. Those should be kept cut off to avoid taking nutrients and outcompeting the original grafted branch. Ultimately this can result in the death of the Kaffir top, leaving only the grafted root portion to continue growing.
This article will explain this process common to all citrus that are grafted: https://www.gardeningknowhow.com/edible/fruits/lemons/suckers-on-lemon-trees.htm
