understanding TS17900100 on HCM workflow

Hi,

I am having trouble understanding this task on the workflow.  I'm new to HCM and having a hard time understanding the workflow in our clients.

I'm checking on this

In this explanation, it seems to only do is create, edit or delete data on the form.  but wouldn't this Task also save the data in the infotypes tables?  How do you define that the form is for create, update or deletion?
