Nope, not the same, 2 different creators - both are on the forums and in this thread. They worked together on technical knowledge of the SDK, but developed and released their airports separately.
@Ocgineer is the creator of the airport in this thread, and @MJetten is the creator of the airport you linked from https://flightsim.to/file/785/eindhoven-airport-eheh-incl-custom-buildings
Try them both out and pick your favorite, they both put a ton of work into them.
Was to be expected, we both knew we were working on it. I was hoping we could eventually create one whole airport together, maybe one without the buildings and one version with buildings for a fee for his Max3D license and effort. In any case, I continued working for the sake of at least having an airport available until Jetten could release his, and in the meantime we got a lovely Eindhoven Scenery project going as well!
Anyway, it seems we are both not done yet anyway, I am currently working on cleaning aerial images to create a separate version for those that want it and I am testing living world to have items and staff spawn randomly on a specified position around (empty) parking spots, which is scaled with the in-game settings so it doesn’t necessarily load users with lower spec computers.
Oh and my next version will have corrected slope of the runway and placement of the glide slope height. I totally overlooked the documented threshold offset and the distance from threshold to GS which I am using now, so the whole runway placement with ILS and GS is as documented, not guessed values.
I think both airports have their pros and cons.
Ocgineer has definitely been a great contribution with figuring out how the ILS was supposed to be configured (so thank you!)
At the moment I’m not planning on doing any aerial images as i find it hard to get a clean transition (so you can see where the different imaging starts).
I’m sure Ocgineer will figure that area out and have an awesome airport for those that are interested in that area!
Also his ILS is more spot on then mine, so props for him there as well 
As said, both have their pros and cons!
To those looking for more Eindhoven scenery, I just released a TU/e scenery pack as well which has a lot of the buildings of the TU/e in it. Some of the models are outdated (like MetaForum and Luna) and some buildings are not modelled (like Flux) but I think it’s a good start. You can find the pack here.
Maybe I am lost 
Is this is related to the eindhoven-scenery-1-1_OFxn3.zip file you released?
The TU/e scenery pack is an “extension” to the previously linked Eindhoven Scenery focusing on the buildings of TU/e only for those that want it.
It is split from the Eindhoven Scenery pack just to reduce potential loading issues for people so you can choose to add the TU/e scenery pack in combination with the Eindhoven Scenery or not.
I’m also frustrated about the problem of instrument approaches not recognized by ATC. They just assign me visual approaches and ask me to tell when runway in sight. Would you like to share your findings about this? Here is my corresponding codes, thanks in advance

Is there something missing or getting wrong? All the waypoints are declared as “NAMED”
Has nothing to do with EHEH
IKKM is DME (IKKM) MALACCA
All other "fixed"are unknown in the sim.
What are you doing? Create a new case in a appropriate section please
Maybe a suggestion. Could you take a look at airport Eelde? In stead of a military airport like De Kooij. Eelde is quite of from reality. There is no tower, there is a runway wich is in real live a taxiway, hangars are rubbish. EHGG is actually an important Airport.
