Does AWS EC2 Auto-Scaling add new instance exactly like current one?

When EC2 auto-scaling group adds a new instance, is it adding one exactly like the current instance (assuming you only have one as a baseline) including any changes you have made post launch, or does it start one that is identical to the first instance's initial state?

It will launch whatever AMI was specified in the Launch Configuration. All instances launched by the ASG launch configuration will be identical to the state defined by the AMI.

See https://docs.aws.amazon.com/autoscaling/ec2/userguide/LaunchConfiguration.html
