​I suspect that the counter to which that value is being compared also
wants to be an INT and if one checks for "val > INT_MAX" then val cannot be
restricted to an integer (and since we are capturing time we need some
unknown buffer).

As for the post question: What can I do if I want to log even
longer-running queries on a data warehouse?

The answer is "nothing special, anything running longer than the supplied
value will be logged". What you cannot do is choose not to log a subset of
queries that take longer INT_MAX/1,000 and less then infinity - once you
hit INT_MAX/1,000 you must log it.
