The connection might be intermittent, and someone was trying to fix a "reset" problem.
I'd advise swapping out ALL of the caps/bridges as it's really not necessary.
Some folks will reply with "caps have a service life of 10 years"...sure...but most times, hobbyists don't have the ability to remove the snap caps without damaging the through holes as is evidenced by the board you've pictured.
The only caps I change when a board comes in for bullet-proofing are C2 (12V circuit, leaks), C4 (5V circuit, contributor to resets), C5 (5V circuit, contributor to resets). If the bridges are working, I leave them. It's infrequent I see a board with a failed bridge.
I know others will disagree. But I'm in the "if it ain't broke, don't mess with it" camp.
Evidence: the two caps that are adjacent and horizontal from each other are 15,000uf caps connected in parallel, which yields 30,000uf capacitance. Those two caps filter the lamp matrix power, the same as the old 30,000uf cap in WMS System 3-7 games. How many times has anyone ever changed out that capacitor?
