No, it means that an email sent from person A to person B, BCC to person C and person D will appear:
Person B:
From: A
To: B
_____
Person C:
From: A
To: B
Bcc: C
_____
Person D:
From: A
To: B
Bcc: D
_____
I.e. as a bcc recipient, the bcc line will only show you - no-one else, presumably so people can get a warm fuzzy feeling that they were specifically bcc'd and didn't receive it as a raw forward, or by accident.
(When there are multiple recipient addresses in the "Bcc:" field, some implementations actually send a separate copy of the message to each recipient with a "Bcc:" containing only the address of that particular recipient.)"
..... i.e. most simply won't bother sending a Bcc line, but some will actually make one, containing that particular recipient only
