Note, the <<EOF isn't necessary in a script. It is here simply to indicate
that the input is terminated.

read a b

Is needed, no more.

In the first example, <<EOF IS needed because thi is a "here document" where the input to the read command is taken from the script body, not the input of the script.

Without the <<EOF then "read a b" will read from stdin.

But I agree it could be clarified that this is intentionally both an example of read and of here documents in one.
