No. You will not arrive at T2. Nobody does. T2 is not a real terminal: it is only for check-in. After land-side check-in, all departing passengers are rerouted to T1. Likewise, all arriving flights are fed into T1, whatever the airline. Once you get off the plane, you can walk to the SkyPier counter, and hand over your luggage tag: staff will go pick it up for you, and put it on your ferry. You can claim your luggage in Macao.
Likewise, when you leave Macao, you will check in at the ferry pier, and the ferry will take you to the international area, and after passing through security checks, you will be sent up to T1. VietJet Air is one of the airlines that participates to this "Macau express link service" program.
