QF, 8 teams, 7 possible opponents. 6/7 chance of avoiding each other, 85.6%. Chance of avoiding each other in first 3 rounds = 96.8% x 93.3% x 85.6% = 80%
Semis, 4 team, 3 possible opponents, 66.7% chance of avoiding each other. So overall a 57.1% chance of avoiding each other for a season.
Four seasons in a row that's 57.1% x 57.1% x 57.1% x 57.1%, a 10.7% chance. Unlikely, but hardly significant.
