Indeed it does, I wasn't aware that vim supports sftp as well.

Hi, SCP is not an internet protocol -- it is simple protocol that is used inside of encrypted SSH session, similarly to SFTP protocol. The name comes from RCP which actually was unencrypted internet protocol and which is hopefully gone.
