I think you probably started google maps first and the GPS took a bit of time to place you accurately. When you started iOS maps it had gotten its satellites in order and was able to place you correctly. As holymadness says, GPS data is the same for both apps.
Obviously you are much wiser than me and you check where your app is taking you BEFORE running in the direction indicated. I forgot to do that a couple of times with iOS map, with rather disastrous results the last time. Neither app, or any GPS app/device for that matter, should be trusted blindly.
