No.
The structure is exactly what we've seen in football tournaments for 40 years. Four groups of four, top two teams from each group qualify and play-off in knockout rounds, like so:
Group A
A1 A2 A3 A4
Group B
B1 B2 B3 B4
Group C
C1 C2 C3 C4
Group D
D1 D2 D3 D4
Quarter-finals
QF1 - A1 vs C2
QF2 - B1 vs D2
QF3 - C1 vs A2
QF4 - D1 vs B2
Semi-finals
SF1 - QF1 winner vs QF2 winner
SF2 - QF3 winner vs QF4 winner
Bronze medal match
SF1 loser vs SF2 loser
Final
SF1 winner vs SF2 winner
The problem here was that the groups A & C had a Chinese top ranked pair (world #1) and a South Korean top ranked pair (world #3) along with another South Korean pair.
Knowing the other South Korean pair would be likely to lose the match and face the top ranked South Korean pair in the QF3 match (C1 vs A2) - limiting the number of possible medals for South Korea by eliminating a pair before the Semi-finals - the top ranked South Korean pair didn't want to win. Knowing that they didn't want to win, the Chinese pair didn't want to win because they'd end up facing them (A1 vs C2). The other South Korean pair would then end up winning and facing the top ranked pair (A1 vs C2) so didn't want to win and the fourth pair - the Indonesians - would end up winning and playing the world #1 Chinese team (C1 vs A2).
