Sorry, but I don't see the confusion.
The phrasing is "Your speed becomes 2" which is much different from "You are prevented from moving more than 2 squares in a round".
Running says "Move up to your speed + 2". To me, it isn't hard to see your maximum Slowed movement in a round thus becomes 4 plus 4 plus any shifting you might do for a normal total of 9 squares per round.
Remember moving anything more than 5 squares brings non-trivial penalties. Those four extra squares are not always worth it.
This doesn't mean setting a hard limit on 2 squares moved is necessarily a bad houserule, only that Slowed becomes a crippling condition, much worse than intended.
