If a device is powered up (generaly means not in standby) it asserts the signal. Other devices look at that signal they use it to decide wheter to receive signal from one source or another. Ig you connect several scart cables into a passive cheap scart multi way adaptor (bit like a duraplug 4 way power adaptor ) things get complex , lord knows what asserts the signal, what ignores it, & what reads/ obeys it. The signaw by the way is a simple DC level, not a video signal, Its equivalent of a semaphore flag Up or Down, thats all. Imagine a gang of men on a road, some shovin a red flag up, some pulling it down to colour & some cars & workmen ignoring it & moving cars & tarmac where they want regardless of the flag. The Scart flag was designed for simple end to end use: just 2 devices, not up to 4+1 devices sharing. Here's some scart pinout stuff (via a search engine):
