IMHO through means all the way through. If you cut a through dado on a
board you have two pieces left over. Think through mortise
The OP said these were not through dado's so a stacked dado would not work.

Shelves are typically embedded into stopped dado's The stop is near the
front of the cabinet and a notch is cut out of the front ends of the
shelf back from the front of the shelf about the length of the part of
the dado that is not full depth.
