Hey, I was concerned with that as well and found the following code here on the forums that appears to work:
[wpv-if evaluate="'[wpv-current-user info="id"]' = '[wpv-post-author format="meta" meta="ID"]'"][cred_link_form form="Edit Listing" text="Edit Listing" target="_self"][/wpv-if]
Hope that help, obviously replace Edit Listing with whatever your form name is :p
