Not to the extent that it allows them to know whether or not they'd actually work as a couple. Comforting someone or even saving their life doesn't make you compatible with them. There is more to relationships than that.
And again, that's great, but that doesn't for a second mean that they can work as a couple. Firefighters and cops will do the same thing, but that doesn't mean they're compatible with everyone on the planet. Lois and Clark have no foundation. They were just kind of brought together because of canon, which is bad writing.
