It stops and fails with the first command that does not return on success. It means
that if the first command fails, the second won't run at all.
To avoid confusion it is recommended to explicitly enclose the commands in
double quotes. For instance if the command is false (without double quotes) it will
be interpreted as a boolean by the YAML parser.
