AJAX 2 way dimmer wiring

I'd like to replace the existing top and bottom landing switches for a set of AJAX 2-way smart dimmers.
Before I splash out, I thought its best to understand if these dimmers are compatible with the existing wiring.
The lighting circuit is wired in the 2 plate method with neutrals available at the switches and a 3-core cable between the two.
The issue I'm having is the manufacturers wiring diagram does not seem to represent the wiring arrangement I have.

Manfacturers wiring diagram:


I envisaged with my wiring topology that it would resemble something closer to this:
(Bear with me, Its messy but I don't do this for a living or have the proper software)



I contacted thier technical support but they weren't much help and responded with a blanket statement, referring me back to their diagram. Being a European company (Ukraine) I imagine its a case of not understanding alternative UK wiring methods and so am seeking advice here. The reason I believe this is because their diagram would appear to be adequate for a property wired in singles as John Ward describes HERE (6:01 - 9:46). Later in the video he goes on to show 3-core wiring between 2-way switches as I've attempted to demonstrate above.

Could anyone advise if these 2-way switches will function if wired as I've shown or have I made a complete hash of it?

Best Regards
