Example. Call with 

context —mode=FR

- Uncomment the first commented lines. Compilation fails because mode FR is on so that works

But I get English anyway. Uncomment the second commented part and it fails, but it should not because mode=EN is not turned on.

%\startmode[FR]
%  \BLURBONE
%  \stopmode

\startnotallmodes[FR,RU]% english is the default
\enablemode[EN]
\stopnotallmodes

\startmode[EN]
%  \BLURBTWO
\setuplanguage[en][patterns={en}]
