According to the Shimano tech docs, you set it on the large cog, but then you check it to make sure it's not interfering with the small cog.
A RDER designed for an 11-34 cassette probably won't exhibit any problems, but put on a 12-23 or similar and it might.
"4. How to use the B-tension adjustment screw
Mount the chain on the smallest chainring and the largest
sprocket, and turn the crank arm backward. Then turn the
B-tension adjustment screw to adjust the guide pulley as close to
the sprocket as possible but not so close that it touches. Next,
set the chain to the smallest sprocket and repeat the above to
make sure that the pulley does not touch the sprocket."
