This feature shows you the Matching Profiles. Match will be selected based on the criteria you mentioned in My Partner feature.

For example, if you choose 'Doctor' as your choice in 'Occupation' category for your partner, then 'Auto Match' feature will show you all 'Doctor' profiles which are compatible with yours. If you also choose 'Height' and 'Colour', then this feature will show you only those profiles whose occupation is 'Doctor' and whose 'Height' and 'Colour' matches your criteria.
