We would like to add a couple dummy commits to the consumer_class branch, so that it will have more than one commits that are different from the master branch:
git checkout consumer_class
touch dummy.txt
git add dummy.txt
git commit -m "Add a commit" --date="2017-02-01"
git rm dummy.txt
git commit -m "Add another commit" --date="2017-02-02"
Now, when we run git log --graph --all --pretty=format:"%C(auto)%h %ad%d %s" --date=short again, the following is the output:
* f46d89f 2017-02-02 (HEAD -> consumer_class) Add another commit

We got the output shown above. Why is this the case? It seems very weird because the date of the latest commit on consumer_class, which is f46d89f 2017-02-02 (HEAD -> consumer_class) Add another commit, is actually less than (earlier than) the date of the latest commit on master, which is 87b5f13 2017-02-26 (master) Put received locations into a queue. So how does this make any sense? Why would an earlier commit be listed before a later commit?
The answer is because Git lists them according to the "committer date", instead of the "author date". That is, the date specified with the --date option in git-commit, as well as the dates shown by running the git log --graph --all --pretty=format:"%C(auto)%h %ad%d %s" --date=short is the "author date", as opposed to the "committer date". Since git-log lists (orders) the branches w.r.t the "committer date" of the latest commit of the branches, the consumer_class branch became the first in order, since the "committer date" of the commits that we added are actually today's date, which is the date at the time that we ran the git-commit command. We can understand this better by running the following git-log command, which shows both the "committer date", as well as the "author date":
$ git log --graph --all --pretty=format:"%C(auto)%h Committer Date=%cd Author Date=%ad%d %s" --date=short

As we can observe from the output, the "committer date" of the latest commit in consumer_class branch is later than the "committer date" of the latest commit in the master branch. Hence, the consumer_class branch is listed before the master branch.
To demonstrate that it is indeed related to the "committer date", let's add the same commits to the consumer_class branch on a fresh copy of the repository, but this time with a custom "committer date":
$ cd ..
# Checkout a fresh clone of the repository
$ cd repository

Now, let's add some commits to consumer_class branch, but this time with specifying the "committer date" (instead of, or in addition to, the "author date"):
git checkout consumer_class
touch dummy.txt
git add dummy.txt
GIT_COMMITTER_DATE="2017-02-01 12:27:46" git commit -m "Add a commit"
git rm dummy.txt
GIT_COMMITTER_DATE="2017-02-02 12:27:46" git commit -m "Add another commit"

$
As you can observe, the consumer_class branch didn't become the first in order this time. The reason is, the "committer date" of the latest commit in the consumer_class branch is 2017-02-02, whereas the "committer date" of the latest commit in the master branch is 2017-02-26. Since the "committer date" of the latest commit in the master branch is greater than the "committer date" of the latest commit in the consumer_class branch, the master branch is listed first in order.
Note that even though the "author date" of the latest commit in the consumer_class branch, which is 2021-02-24, is way later than the "author date" of the latest commit in the master branch, which is 2017-02-26, the master branch is still listed first in order, since the listing order depends only on the "committer date" and not on the "author date".
