This type of question allows one or a series of questions to be answered multiple times, without limitation.
This question creates a kind of “response loop”, which ends when the user finishes the sequence and moves into the next question.
One way to visualize it is by imagining a box with multiple columns of variables that have an indefinite number of blank rows.
Imagine for example that you need to control the quality of different types of trees. It is not clear how many trees will be reviewed, but the information to be reported was defined: the diameter of the trunk, the color of the leaves, and the state of the bark. The user can answer this information as many times as necessary and then, when finished evaluating this item, can continue with the following questions on the form.
Another example of the usage of this question is when you need to take pictures for an incident report or the result of an installation, but it is not clear how many photographs you will need. In this case, just add the question "Photo" inside of a subform, since it allows an indefinite number of responses.
