That is most interesting, as ":h modeline" describes that they comprise only
"set" directives, not arbitrary commands. I.e.:

{options} a list of option settings, separated with white space
or ':', where each part between ':' is the argument
for a ":set" command (can be empty)

after the:

{vi:|vim:|ex:} the string "vi:", "vim:" or "ex:"

It doesn't even allow the '|'.

How turning off modelines might help to execute commands in modelines is
a guessing game, without documentation of supported behaviour.

Admittedly, on the few occasions that an arbitrary command seemed to be
needed, I've found another way to achieve the result.
