Surely it depends on how the decision to look both ways was made? If you do it out of instinct and immediately think "oh yeah, forgot I only need to look one way" then it wasn't logical. But if you know it's one way, yet think "I've witnessed bikes and even cars going the wrong way before, better check both directions" that seems like it could be a perfectly logical action.
