Because of this quote:

RFC 2616 section 8.1.2.2 Pipelining:

    Clients SHOULD NOT pipeline requests using non-idempotent methods or
    non-idempotent sequences of methods (see section 9.1.2). Otherwise, a
    premature termination of the transport connection could lead to
    indeterminate results. A client wishing to send a non-idempotent
    request SHOULD wait to send that request until it has received the
    response status for the previous request.
