Moving mutually into supporters' territories?

Hi all,

This has been bugging me, apologies if it's been answered before but I couldn't find it.

Let's say we have:

Germany:

Tyr->Trieste

Vienna support move Tyr -> Trieste

Austria:

Trieste -> Vienna

Budapest support move Trieste -> Vienna

Will everything succeed here? I know direct swaps aren't allowed but this isn't direct per se!
