Yeah, I
think, if my maths is correct
, that you can press two buttons in either mode:

Just like the original Dimension effects, the DC-2W offers a simple and direct interface with four preset switches that provide sonic variations with increasing width and depth. While the originals had mechanical switches, the DC-2W is equipped with modern electronic switches and status LEDs for more solid performance. The new switches also allow you to press two at once to access a variety of additional sounds. Across the DC-2W’s two effect modes (S and SDD-320), 20 different Dimension variations are possible with just four switches.

Despite players trying, pressing multiple buttons on the DC-2 didn’t actually produce any sound variations. Similar to SDD-320 mode, pressing two buttons at once in the DC-2W’s S mode provides access to six different “in-between” sounds not available on the original DC-2.
The DC-2W’s SDD-320 mode fully captures the original Dimension D vibe in every way. Many engineers like to press multiple buttons on the Dimension D rack for new and different sounds. But in truth, only two actual sound variations are technically possible with this undocumented feature. With its modern switching, the DC-2W’s SDD-320 mode enables six sound variations when two buttons are pressed, including four “in-between” sounds and two all-new voices.
