Well.....I think she did really well and I take my hat off to her.....if only for staying calm.
I think she did well, she missed the car and that's the important bit.
..... she did not brake, she just delicately steered the bus around the obstacle (car) and did not panic.......
When interviewed she said she did brake. She came off the brake when the bus slewed, which thankfully put her in a perfect line to avoid everyone, which can clearly be seen on the footage. She admits that luck was on her side, and to be honest we all need a bit of luck in these situations.
Personally I think it matters not one jot, she avoided a collision by whatever means so the rest is irrelevant. Without the presence of the dash cam footage we wouldn't even be able to scrutinise.
I'm with STEMO, I think she did well. It was actually a very graceful slide, I'd have been well chuffed if it was me.
