Help me understand, is this normal?

My 14 week old great Shepard piddles every time I come home and if he’s feeling lazy and I walk up to him. If he’s in a playful mood he will play fight, come and just be full of confidence but when I first come home after a short period (usually he’s only alone for an hour-two max) or if he’s been laying down and quiet he gets so nervous and his energy is shifted almost like he’s terrified of me. It’s like he has a split personality and I just don’t get it 😅😅 is it normal? I did accidentally kick him while walking and I have dropped-tossed him while trying to carry him in with something else unintentionally before I realized I should try carrying him in with things but we don’t hit him or beat him. Mostly if he’s done something wrong we just say his name. However my toddler attacks him if amped up too much but he has absolutely zero fear of him and sees him as either equal or maybe even below 🤔 and of course we try to catch the act and curb it immediately every time but like I said Willie (puppy) has no fear of this tiny human he can push over with one paw.

I’ve never owned a Pyrenees I’ve always been a husky person so I just don’t know the personality at all.
