By general need on

The process of upgrading is outlined as:

1. back up
2. unzip 5.2 files onto my server
3. run update.php

What does step 3 do?

I recently upgraded and then after some issues decided to ‘unwind’ the upgrade by deleting all files and folders from the 5.2 tar ball (step 2) and replacing with my old files and folders from my back up that I had made in step 1. But since I had also performed step 3 I am unsure as to whether I upgraded or not?

Sometimes new columns are added to the database

I would add
2A. Put your site in maintenance mode
2B. Disable non core modules

As far as I know step 3 updates only your database. Not always needed, not sure in your case, this also depends whether you updated from 5.1 to 5.2 or from a previous Drupal version (can't remember whether there were any database updates from 5.1 to 5.2)

Here.

In the red block you can see some test for apache version removed (too many apache servers out there concealing or reporting a wrong version),

The green block shows that only a "created" key and an index was added to 'users'.

It seems harmless, but don't make it a habit.
