Yes it does, looks like they have a lot of products in common. So probably buying from the same supplier

Also looks identical to the Wren stems, though Wren seems to be claiming slightly lower weights for a given length...

To be fair, once your talking about light, cheap forged aluminum stems, a lot of resellers are likely sourcing from the same OEM.

They should flex roughly as much as expensive light aluminum stems, but are maybe more durable

in what way would they be more durable?

on a mountainbike, is it even possible to feel the flex from the stem separately to..tires, fork, all that?

by the way, what really sucks on light cheap stems are the bolts, which are in my experience single-use

The stems above - and most cheap stems - are forged, which will (very generally spoken) result in a stronger part compared to machining, which is how expensive stems are often made.

Why then someone's going to pay 100-150euro for an expensive one stem that eill be lees stronger than a 3d forged light stem?

Because it's lighter or looks cool. Everyone has different priorities.
