Just because ConTeXt fixes your mistake doesn't mean you should abuse it 
and *no* user should learn from your example.

Each ConTeXt document should contain a starttext/stoptext  pair or 
equivalent commands (e.g. startdocument/stopdocument or 
startproduct/stopproduct).

And now it gets even worse, see 
https://meeting.contextgarden.net/2021/talks/2021-09-21/starttext.pdf 
why \starttext is necessary.
