Yes it does but that in the first instance requires stairs or bridge in place. In the second it uses the slides anyway although it's supposed to be "controlled" ( yeah right that's going to work!! )
Unless multiple stairs met the Aircraft and were able to be placed very quickly I wouldn't be sitting on my hands hanging around.
This SQ A330 incident was apparently a real Fire and for the life of me I cannot see why they didn't take the first opportunity to get the hell off the Jet.......
Ignorance is bliss I guess and luckily this time it worked out ok.....
