I'll start out by saying that I clean my brass before I resize them. But I use corncob/walnut media too, not the SS pin setup that you're using.
With corncob or walnut media, you can and will get pieces of media stuck in the flash hole that will cause misfires if you miss one before you reprime/reload.
With the SS pin stuff It sounds like that problem is non-existent so if you like to deprime before cleaning, then it should be perfectly fine to do so.
I would definitely make checking that the flash holes are clear a step in the reloading process if you haven't already.

My next comment is unrelated to your cleaning procedure but by reading your posts here as you've gotten started in the reloading hobby I see that you do have an extreme close attention to detail.
Now...I might just throw you into fits by mentioning this, but if you're loading mixed brands of brass, as pictured above, you're introducing a whole lot more inconsistency than you'll get from your current reloading process.
Different brands of cases will vary in internal capacity, neck wall thickness and ductility of the brass (causing differing neck tension).
You might want to check into segregating your brass by brand if you're looking at another step towards making more consistent ammo.
Myself, I'm about as meticulous as you are (trim length, seating length, etc down to 0.0001") when it comes to rifle ammo, so I do understand your attention to detail.
But for the majority of my pistol ammo, I load mixed brass and tend to stick with somewhat looser tolerances since I'm loading and shooting a lot larger quantities and the time becomes a factor.
Don't take this as me discouraging you from your detail level...everyone develops their own preferences and "system" for how they load.
Note I didn't say anal-retentive...although that IS how I describe my rifle reloading procedure. There are quite a few times that I wonder why the heck I just spent 4 hours crafting only 50 rounds or less!
