Gerben,

\startnotallmodes is behaving as it should. Here, it is not the case 
that RU and FR (all the listed modes) are set, so EN is enabled, and you 
actually have both FR and EN set.

Try the following with

        context —mode=FR

and make sure you understand the result.

    \starttext
    \doifmode{EN}{EN is enabled\par}
    \doifmode{FR}{FR is enabled\par}
    \doifmode{RU}{RU is enabled\par}
    \doifmode{FR,RU}{at least one of FR and RU modes is enabled\par}
    \doifmode{EN,RU}{at least one of EN and RU modes is enabled\par}
    \doifmode{EN,FR}{at least one of EN and FR modes is enabled\par}
    \doifmode{EN,FR,RU}{at least one of EN, FR, and RU modes is enabled\par}
    \doifnotmode{EN}{EN is not enabled\par}
    \doifnotmode{FR}{FR is not enabled\par}
    \doifnotmode{RU}{RU is not enabled\par}
    \doifnotmode{EN,RU}{neither EN nor RU is enabled\par}
    \doifnotmode{EN,FR}{neither EN nor FR is enabled\par}
    \doifnotmode{RU,FR}{neither RU nor FR is enabled\par}
    \doifnotallmodes{FR,RU}{all of FR and RU modes are not enabled\par}
    \doifnotallmodes{EN,RU}{all of EN and RU modes are not enabled\par}
    \doifnotallmodes{EN,FR}{all of EN and FR modes are not enabled\par}
    \doifnotallmodes{EN,FR,RU}{all of EN, FR, and RU modes are not
    enabled\par}
    \stoptext

Then, add the following block to the beginning of the file and try again.

    \definemode[EN,FR,RU][keep]
    \doifmodeelse{EN}
       {    \disablemode[FR]
            \disablemode[RU]}
       {\doifmodeelse{FR}
        {   \disablemode[EN]
            \disablemode[RU]}
        {\doifmodeelse{RU}
          { \disablemode[EN]
            \disablemode[FR]}}
          { \enablemode[EN]}}

I find it useful to add such a block to the environment of every file 
that uses mutually-exclusive modes. This version pf the block sets a 
default value if none is on the command line.
