that's absolutely right. Sniffers/Protocol Analyzers like Ethereal are best
admirer of this mode.
as soon as u start Ethereal or xyz sniffer and select a perticular card,
that card will be put up in promiscuous mode and that's how u get whole
frame from network even the frame which your machine was not supposed to
see, can be seen with that. and when etherreal is closed, you start getting
only the frame which were intended to your machine.
** my comments are not for 802.11 network cards **
