I'm telling you what actual goal he had, in the actual play of the game that I'm reporting on.
There is no "simulation" to be broken.
A "con" is a downside or a problem with something. The fact that the player was able to establish, via his action declaration for his PC, that the runes revealed a way out, is not a downside or a problem. It's part of what makes that particular system worth playing. If I want to play a different sort of RPG, then I can do that too.
Also, the "kill an Orc" example, here's a thing that the player establishes, when their PC kills the Orc: they establish that the Orc didn't dodge. And this is not a ubiquitous feature of RPGs: in RuneQuest, the player doesn't get to establish that. The GM, controlling the Orc, gets to make a dodge or parry roll. Which we could structurally compare to the GM making a roll on the Strange Runes table.
This is why I say that (i) the boundaries are subtle, and not easily drawn; and (ii) that for some posters, they seem to conform very strongly to how they are familiar with D&D doing things.
But imagine someone who responds to the Orc dodging issue as you are responding to the what do the strange runes say issue, and you will understand why so many players of RQ, RM, and similar "mechanical simulationist" RPGs have trouble taking D&D combat seriously.
