I think the exception applies to the phrase "after being declared out" on the D3K. Think about it. You've got one knee up in the air, your left fist pointing at the scorekeeper in the front row, your right fist beside your bosom and you are saying, "harggggh" loudly enough for the bus driver to hear. But, there is an optic yellow orb on the ground and the batter is taking off to first. If first is unoccupied or there are 2 outs, she is the exception, declared out and running. If the D3K is not in effect and she runs, you should be declaring her out loudly and clearly enough for the infield to hear especially F2.

So if R1 is on 3B and R2 is on 1B and there is one out, there is no situation when a BR would be running on a D3K and therefore no exception to the interference rule. If she does run and draws a throw from F2 and the ball ends up in RF. Don't you have a Dead Ball and interference? The runner on third is out?
