[O] Text above first headline is being exported, despite :export: tag being used.

At

http://orgmode.org/manual/Export-settings.html

I read

,----
| ‘SELECT_TAGS’ 
|     The tags that select a tree for export (org-export-select-tags). The
|     default value is :export:. Within a subtree tagged with :export:,
|     you can still exclude entries with :noexport: (see below). When
|     headlines are selectively exported with :export: anywhere in a file,
|     text before the first headline is ignored.

But I have trees tagged for export, while text above first headline is
being exported. Can anyone confirm?
