Does DDC perform complex multiplication?

GNU Radio

I found two diagrams which seem to indicate different kinds of
multiplication:

I hope the DDC performs complex multiplication because I am feeding it
with one real signal (via BasicRX A:0) and would like to use both I and
Q outputs in my application.

It performs the equivalent of complex multiplication.
