Hate to interrupt yet another conspiracy theory but yes, Salzburg and Leipzig did have to do this, a Swiss judge went through both companies and made them seperate all shared assets and people who worked for the group/both clubs in scouting or business roles were made to just work for 1.
Because they did that, they didn't fail article 5.
IMO the biggest potential problem for CFG is sponsorship. The RB clubs had to split their sponsorships in a way that satisfied UEFA's CFCB. Shared sponsors is kind of core to the whole CFG project.
