Notifying the readers about the change in default value in context example

The example given for context (Passing Data Deeply with Context) starts with a default value of 1. Later on, for explaining 'Using and providing context from the same component', it is changed to 0 and remains the same for a later subtopic too.
While I was going through the example, I was left confused about how the code (shown in the below screenshot) is working given that the default value is set to 1 until I checked the 'LevelContext.js'.

While one can look at the 'LevelContext.js' and check, I think it would be better to make readers aware of the change! We can add a small sentence like 'Note that the default value is changed to 0'

Comece pelo exemplo “Passing Data Deeply with Context” e compare o valor padrão exibido com LevelContext.js; depois, leia a subseção “Using and providing context from the same component”. Adicione uma breve observação no ponto em que o exemplo muda para 0 e confirme que a subseção posterior continua consistente com essa explicação.
