It works /= it's a problem
And since everyone seems to love examples so much, I'll give a couple of it not working(looked through a couple US leagues) :)
Not amazing examples, but what I could find while browsing(also no offense to any of these managers, and if my take is wrong in any way feel free to correct it-just going off what I can see)
(29864) Season 17 dominates D.III, tanks in D.II season 18, seasons 19-20 is stuck as middling playoff team in D.III
(29230) Could take a season or two to tell on this one whether it worked or not. Season 15 absolutely destroys D.III 22-0, Season 16 tanks out of D.II 0-22, Season 17 finishes 5th in D.III, Season 18 relegates to D.IV(on purpose), season 19 promotes back to D.III, Season 20 in a fight to promote back to D.II
(23325) Joined in season 2, basically bounce between D.II and D.III from seasons 5-14, decides to tank for first time in season 15, apparently tanks season 16 too down to D.IV, Season 17 promotes back to D.III, Season 18 demotes back to D.IV, Season 19 promotes back to D.III, Season 20 middling playoff team in D.III
