Yes.

Yes, the .sav is for the "save current state".

No, see below.

If you have no snapshots yet and take a snapshot, then the logical "snapshot"
of the VM's hard disk *is* the base VDI file, now
frozen.
There is not a separate VDI created to store the old disk state; that is stored
in the now frozen base vdi.
The differencing VDI created is to store future CHANGES going forward *after*
the snapshot.
Again: a snaphot is made by freezing the base VDI and all current differencing
disks, and then also creating a new differencing
disk for any future changes.
There is an old link:
http://forum.virtualbox.org/viewtopic.php?f=24&t=8046
(scroll down to "Q. So what about snapshots? How do they work?" ... but NOTE
this link does not make a clear enough distinction
between "snapshots" and "diffencing disks", which can cause confusion.)
