What is the difference between the two?

  $NAME         Replace by the value of the environment variable NAME, or by the empty string if NAME is not defined.

  ${NAME}       Replace by the value of the environment variable NAME, or by the empty string if NAME is not defined.

The descriptions look the same to me.
