@Loh Jane,
Then the website would seem to be in error. My preference or suggestion would be to keep the parallel construct and use the word
performs or switch to
initiates.
Lastly, from the context you provide
form doesn't
exactly mean begin ... it means to formulate, put together, give shape to, put in order or proceed.
Furthermore, more appropriately, you don't form obligations. You may, however, perform them...initiate...or complete them.
