Are MATLAB updates supersed each other or we must install the whole packages?

For example, in Matlab R2019a release there are six updates as shown in this link
For Windows
  • Update 1 = 1010 MB
  • Update 2 = 2.51 GB
  • Update 3 = 3.31 GB
  • Update 4 = 4.12 GB
  • Update 5 = 7.89 GB
  • Update 6 = 8.35 GB
Furthermore, if we take a look on the Bug Reports page of R2019a release
If we download the update 6 package, we'll get all of the previous updates, isn't it some kind of redundancy or a must?
Does it mean that each update package address different bugs and not supersed each other?
I mean, 8 GB is quite a lot for an update, I thought the update 6 package supposely only need 1GB because it superseed the previous update packages.

Update 6 includes all of the previous updates. After updating with 6 all of the changes from 1 through 5 will also be done.
If the question is how this is achieved, the answer is that update 6 includes all of the files updated by the earlier updates, but does not run the earlier updates in sequence.

Each update includes all the previous updates, you only need to install the latest even if you haven't installed the previous ones.

After update 2019b update 2 has been released. I've just realized that "R2019b" folder on Update 1 Package and on "R2019b_Update_1" folder on Update 2 Package has different size and file/folders count.
Thus I conclude that any newer updates, as well as cummulative, the folders are also superseding older updates.
In my opinion, the folder structure to seperate each updates folder even though it's not exclusive each other is unintuitive, so much so that it makes me want to raise this question. Pardon for the inconvenience.
