I used it for
SELECT, INSERT, DELETE, UPDATE, FETCH and COPY_TO statements.
Seems that I was wrong using "DML" for all of them.
They are statements for data management and querying.
Server computes snapshot only for them.
Anytime when I used "DML" in docs it was related to this,
i.e. to the time of snapshot calculation.
