That cap refers to efficiency on the most part.

When an Enhancer practices hadoken with a an Emittor, the Enhancer will never perform the attack on the same footing as the Emittor, assuming they undergo the same training routine and with same-y level of talent. The Enhancer's hadoken would cost more Nen to use, and deals less damage; the differences can be covered by more training for those who are just using Nen categories right next to theirs (exclusing Specialisation), but the differences can be ver drastic once you start jumping 2 steps from your category.

Nen categories far away from the person's own are very hard to develop because they would feel too unnatural while training them; kinda like forcing a natural athelete to get a PhD in chemical engineering, it just won't mix well unless there is a strong will to do it on the person's part. L
