How come it can be different?

With you showing only small code fragments, it's rather hard to say. It's kind of like the old joke:

Goofus is searching for his diamond ring under a streetlamp.

Gallant comes to help, and after about 15 minutes, he says "Hey--about where were you standing when you lost the ring?".

Goofus: "Over there in the parking lot."

Gallant (surprised): "Well, then why are you looking over here?"

Goofus: "The light is better."
