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'

Beginne im Beispiel „Passing Data Deeply with Context“ und vergleiche dessen angezeigten Standardwert mit LevelContext.js. Lies anschließend den Unterabschnitt „Using and providing context from the same component“. Füge dort, wo das Beispiel auf 0 geändert wird, eine kurze Anmerkung hinzu und bestätige, dass der spätere Unterabschnitt mit dieser Erklärung weiterhin konsistent ist.
