Thats probably just an accidental association/linking by your brain. When we learn new things our brain creates neural pathways and these become ‘memory’. If there is something that you learn and at the same time it happened to be when you moved to a new house, were on holiday at a different place or perhaps when you met a new person, your brain may go 'you learned this new thing and that place/person/smell/emotion was also there so i will ‘save this’ together as part of the same memory.
Its like playing a game from your childhood reminding you of the music you were listening to at the time you played it, or a skill you learned reminding you of that awesome dinner you grandma cooked because she was staying with your family at the time.
