OK, maybe Turn to Slag is a bad example. It's actually reasonable to downgrade for that one. (I just re-read Pat Chapin's article on SCG, and every reference to
Turn // Burn in those deck lists is, simply, “Turn”.)
And, yeah, “no one plays Turn to Slag” could be fairly convincing, when it's close to a true statement. “No one” is too general to ever be 100% correct, but I'd give it high-90s … and thus, probably downgrade.
Maybe a more extreme case:
3 Boros C
4 Boros R
(written by someone who was obviously in a hurry)
Boros Reckoner seems obvious, and I bet most of you immediately thought of Boros Charm. What about Boros Cluestone? Can we be sure that “no one” plays the new fixer/cycler? Could your decision to downgrade there change over the next few weeks?
Those are the sorts of things you need to take into consideration, when deciding if you'll downgrade, or not.
As for specific examples - a lot of the discussion that led to the current wording in the IPG stemmed from a well-publicized Legacy event, where a combo deck player wrote “Ancient” (Tomb) with his other lands, but had access to Red mana and thus, conceivably, could be playing Ancient Grudge. (He wasn't.)
What's “obvious” to one judge isn't going to be obvious to all judges, but this IPG language does empower the Head Judge to offer a reasonable level of forgiveness to players who aren't trying to abuse policy, but just made a fairly inconsequential error.
Better?
