So let me get this straight... In DSB-SC... both sidebands are
transmitted... but there is no carrier sent at all? Correct?... and the
carrier is re-inserted at the receiver.

Now with the swing set-up... both sidebands are transmitted... along
with the carrier... but the carrier's amplitude changes from extremely
low to a normal AM carrier when the modulation is added.

There is no carrier. It's like listening to LSB and USB at the same time. If
you remove half the ssb signal, say LSB, you would hear more of the donald
duck sound due to the reduced size of the bandwidth. Just forget AM carrier
when talking DSB-SC as it just isn't there. DSB is AM and when the carrier
is removed you have DSB-SC
