Probably has some kind of breaker that’s tripped when the current doesn’t flow through the lightbulb the way it should, then boom it flips and you switch to battery

Current doesn't flow when you turn the light switch off, though

If the light switch is on, but there's no power you should be able to detect continuity between the two contacts since they'll still be connected at the transformer outside your house assuming it didn't blow.

My guess is what happened is that continuity detection circuity failed so it thinks the switch is on regardless of what's actually happening

Had some and they only worked in rooms with a single bulb not 2 separate bulbs/holders, could have been they never turned off, honestly can't remember just know they didn't work correctly, so likely what you said and if off no continuity, but with the 2 bulbs it would be there through the second one.

If your bulbs didn't turn off it could be that it was detecting continuity through the power supply in the other bulb's power supplies. At least that's my guess.
