But in such a case, when we share a public key from server/system B to server/system A, this generally indicates that user from server B is transferring files to server A and not vice-versa.
No! It means that the authentication is done in this direction.
Consider it this way: if you give someone the key to your house he has access to it. That could mean he takes away something or brings something, but this difference is not depending on him receiving your key or not. He could do both these things without the key too, he just would have to ring your bell (and wait till you answer it) if he lacks the key.
If userA@systemA (notice that "userA" on one system and "userA" on another system are two different accounts, they just happen to share the same name) has his key on systemB this user is allowed to log on (without password). What he does after this logon is not determined by the key at all. He could put files (that is: transfer to the server) or get files (that is: copy files from that server).
This is also possible with classical ftp or sftp: there is the put/mput command to move files to the system and get/mget command to move/copy files from the system.
In scp this would look like:
This will transfer a remote file from "system" using the account "user" to the local system. The other way would be:
This would transfer a local file using the account "user" to the remote system "system". The difference between having put the key of your local user on "system" will be: without the key you need to authenticate, with the key you don't.

sftp-server(1M) System Administration Commands sftp-server(1M)NAME
sftp-server - SFTP server subsystem
SYNOPSIS
/usr/lib/ssh/sftp-server [-f log_facility] [-l log_level]
DESCRIPTION
sftp-server implements the server side of the SSH File Transfer Protocol as defined in the IETF draft-ietf-secsh-filexfer.
sftp-server is a subsystem for sshd(1M) and must not be run directly. Command-line flags to sftp-server should be specified in the Subsys-
tem declaration. See sshd_config(4) for more information.
To enable the sftp-server subsystem for sshd add the following to /etc/ssh/sshd_config:
Subsystem sftp /usr/lib/ssh/sftp-server
See sshd_config(4) for a description of the format and contents of that file.
There is no relationship between the protocol used by sftp-server and the FTP protocol (RFC 959) provided by in.ftpd.
OPTIONS
Valid options are listed below. As stated above, these are to be specified in the Subsystem declation of sshd_config.
-f log_facility
Specifies the facility code that is used when logging messages from sftp-server. The possible values are: DAEMON, USER, AUTH, LOCAL0,
LOCAL1, LOCAL2, LOCAL3, LOCAL4, LOCAL5, LOCAL6, LOCAL7. The default is AUTH.
-l log_level
Specifies which messages will be logged by sftp-server. The possible values are: QUIET, FATAL, ERROR, INFO, VERBOSE, DEBUG, DEBUG1,
DEBUG2, and DEBUG3. INFO and VERBOSE log transactions that sftp-server performs on behalf of the client. DEBUG and DEBUG1 are equiva-
lent. DEBUG2 and DEBUG3 each specify higher levels of debugging output. The default is ERROR.
EXIT STATUS
The following exit values are returned:
0 Successful completion.
>0 An error occurred.
FILES
/usr/lib/ssh/sftp-server Server-side binary.
