This should be pretty obvious. In basic terms, it would be extremely inefficient for the brain to store everything "directly." Meaning all memories are "reconstructions" to some extent and therefore inherently flighty given the dynamism of the brain. Said differently, it would be weird if the brain didn't take advantage of the very high-level abstractions we use in our day-to-day for the purpose of efficient memory storage. Anecdotally, one time I re-played in my head an entire movie after I watched it (Astro Boy!) as an experimental exercise, and it was clear that as I was 'recalling' it, the line between "reconstruction" and "direct memory" was extremely blurry, and I could feel my own eagerness to fill in details that may or may not have occurred.
