The heredoc structure is self containing. It is no different than saying 1 + 2 or $a . $b. Heredocs typically end in semicolons because there are the entirety of the statement.
Think of it outside the context of a heredoc. The statement print nl2br ($some_variable); only includes a ; at the end. The same with print nl2br (trim ($some_variable));. By itself trim ($some_variable) would require a ;, but when used as a parameter to a function, using one would throw an error.
