Please correct me if I'm wrong, as I understand it...

The purpose of the vent lines is to keep the float bowl at atmospheric pressure, ensuring that fuel in the float bowl is drawn up through the jets correctly, relieving air as fuel flows into the float bowl. Air or dirt shouldn't flow from the vent lines into the float bowl, no dirt should be sucked in.

With vent lines running into the airbox, if the bike is laid on it's side, when we crash or fall off (about every time I ride!) there is a risk of fuel running into the airbox, obviously not what you want due to the fire hazard.

All the best, Dave.
Warm crankcase + cold water=vacuum. Crankcase breather can suck water into tranny creating a milkshake. Same with carb breathers. Only need to do 1 but I usually do top 2 on carb. Draws water into carb snuffing motor. No breather means all sucking drawing up through carb vents. Mate's 17 TE250 did it last ride. I scolded him about it!

Just run the breathers long enough to loop back downwards(face them downwards). I zip tie mine to subframe rails generally. Just keep them below air filter height so fuel won't leak onto it when bike is sleeping upside down.
