Why would it matter if it says you die? It’s not like there’s a rule that dead characters can’t take actions. Or that they transform into objects. Or get sent to another plane of existence depending on who they worship and their alignment while leaving an object behind.
Honestly, RAW just doesn’t work. If you can’t do anything unless specifically allowed, then you can’t do anything because whatever you do will always be more specific than what the rules say. If you can’t do anything unless forbidden, then it doesn’t work because there’s so much the rules didn’t bother with, just leaving it to common sense. And then there’s the fact that sometimes rules contradict. Sure there’s a rule that the more specific rule overrides the general rule, but that’s just yet another contradicting rule on the pile.
There’s nothing specifically saying whether or not you can move left. There’s nothing specifically saying whether or not you can move through walls. We all know you can do one of those but not the other, but it’s not because of anything the book says.
Granted, the book sometimes gives creatures special abilities that let them move through walls, which would be an odd thing to do if it’s something you can do anyway, but the game constantly goes into different levels of detail about things.
