Are these two tips for my Pinecil the same thing?

I recently bought this customized desoldering tip for my Pinecil:

It comes in two pieces, the tip itself which has a M4 threaded hole, and a TS100 tip to put into my iron that has a M4 threaded screw at the end. There are other tips for other controllers I want to get which are just the top screw-on part and don't come with the TS100 tip.

I noticed that Pinecil also sells a threaded tip, though I am unsure what those brass fittings you screw into it are for:

I am just a little worried if the cheap TS100 tip that I got along with the screw-on tip would be any good. Would it be worth it to get that official Pinecil one and just put the screw-on part of the tip on that instead, or would I basically be buying two of the exact same tip and it's likely the exact same quality?
