The question you're asking, I think, is why WJZ moves from 13 to 11 and WBAL from 11 to 12, when it might appear to make more sense to move WJZ from 13 to 12 directly. The answer is that WVPT in Staunton got moved from 11 to 12, and WVPT is currently co-channel with WBAL; in the repacking process, the FCC permitted existing short-spacings (or short-spacing equivalents) to continue, but did not create new ones. As such, WJZ and WVPT cannot be co-channel, so WJZ couldn't move to 12. WBAL had to be swapped to 12 to maintain the short-spacing with WVPT, and WJZ got dropped on the now-more open channel 11.
If I've lost you, I can try again.
After reading this super slowly, I think I got it! But Staunton, VA is so far away from Baltimore, MD, and since WBAL and WJZ are on the same transmitter (TV Hill) it just seems like it wouldn't make much difference. Thanks, Trip, for the detailed explanation!
