boost.asio's socket's recieve/send functions are bad?

Data may be read from or written to a connected TCP socket using the receive(), async_receive(), send() or async_send() member functions. However, as these could result in short writes or reads, an application will typically use the following operations instead: read(), async_read(), write() and async_write().

I don't really understand that remark as read(), async_read(), write() and async_write() can also end up in short writes or reads, right?
Why are those functions not the same?
Should I use them at all?
Can someone clarify that remark for me?
