Depends on the person, I guess.
One of the reasons Tuchel fell out with the owners was because they wanted the coach to participate more behind the scenes whereas Tuchel himself only wanted to focus on coaching. When Potter came in and the club also hired Brighton's sporting director to join with him, it looked like the owners had gotten their wish by bringing in a coach who was happy to have an active relationship with the directors but that plan unraveled quickly with Potter's failures as a coach.
With Poch I'm not quite sure how much of a role he has outside of managing the first team but the history with Tuchel/Potter has already shown that the club/directors are at the very least open to the manager having a wider role. In any case the sporting directors will always have final say in decisions like transfers, contract negotiations etc. over the manager but as long as there's an honest and open dialoque between the manager and the background organization I wouldn't necessarily see it as some huge problem.
The days of managers being the top dog at their clubs are more or less over and it's not like Amorim would have full decision making power anywhere else either if/when he makes the step up to any of the bigger clubs.
