Does stealing via "Mug" also count towards the Talent for Acquisition trophy?

Solution 1:

The page for this trophy on PlayStationTrophies.org says that you are able to use Mug to earn this trophy as well as Steal.

This trophy is very direct in its wording; with Rikku successfully steal items 200 times. Rikku starts with the "Steal" ability and you can steal from every enemy in the game. This trophy can also be earned by using the "Mug" ability. So keep stealing and this trophy will pop on the 200th successful steal.

This is backed up in the comments on that page as well as other threads, like this one:

I can confirm that 'Mug' also counts towards the trophy as it unlocked when I used mug
