   ```lua
   -- Clears the builder and resets the state. It does not actually clear the backing binary array, it just reuses it as
   -- needed. This is a performant way to use the builder for multiple constructions without the overhead of multiple
   -- builder allocations.
   function mt:Clear()
       self.finished = false
       self.nested = false
       self.minalign = 1
       self.currentVTable = nil
       self.objectEnd = nil
       self.head = self.bytes.size -- place the head at the end of the binary array
   
   
       -- clear vtables instead of making a new table
       local vtable = self.vtables
       local vtableCount = #vtable
       for i=1,vtableCount do vtable[i] = nil end
   end
   ```
   
   what you say `doesn't release memory.` means `It does not actually clear the backing binary array`?
