The only question is: are you growing? Are you achieving your muscular gain goals? If you are, then great! Keep doing what you're doing. Practice is what matters.
Now the theory...
More than 2g/kg is not going to do you much good, except inasmuch as it's part of calories for energy. You'll tend to poo and piss it out, assuming you have enough calories altogether.
Yes, you can absorb a lot of protein in one go. There is some evidence that having many small meals (whatever's in them) is better for you than having a couple of big meals. Better for you in that you have a higher average energy level, and are more likely to put on muscle as a result of your workouts.
However, as a beginner - anyone in their first year of serious training - it won't make much difference. 250g chicken in one big slab of 250g, or 5 meals of 50g each, not much difference for you. So long as you have at least 0.8g/kg protein daily, and consume more calories (whether calories from protein, carbs or fat) than you expend, you'll grow.
Don't worry about the details too much. The "extra" protein past the 2g/kg is just 35g. That's 140 calories, most of a glass of milk, or a couple chocky biscuits. Not a big deal in the scheme of things. Your body is pretty resilient, you can have a wide variety of diets and still do okay.
The major concern with eating over 2g/kg is how much it's costing you in expensive protein powders and/or meat. 35g is not much, it's only the guys eating 300+g protein daily whose wallets will be hurting.
