Because when you write for 1UP, you live in another world. A magical place where logic and sense are thrown to the wind!
But no, it can actually be explained (though you aren't wrong in thinking it's silly). It's kind of a stupid thing to say, as obviously you'd still call this a strategy game, just like you call tactical RPGs SRPGs, not TRPGs, but it isn't entirely inaccurate. Strategy and tactics, while intrinsically linked, are two different things in senses other than genre. Truly, even games that deal with tactics are going to require the player to have some sort of strategy, so it's sort of arguing semantics a bit, but:
Tactics can generally be viewed as the minutiae of active battle, while strategy generally refers to bigger, more sweeping concepts and long-term planning like troop movements, etc. So strategy is the bigger thing which eventually pushes you into tactics, and tactics is, more or less, just the execution of your strategy. You could also use it like: "they were using guerrilla tactics"; i.e. as a synonym for "methods".
EDIT - It occurs to me that in the chess thread, I remarked an example I read a while back about the differences between chess, checkers, and go. Go is all strategy (long-term), checkers is all tactics (immediacy), and chess is a balance of both.
