yes. In tong bei, you hurry your attack one after another till the opponent is defeated.
in ba ji, you do not move lightly, when the opponent comes and presents an opening, you go at the same time and deliver a single fatal or decisive blow/strike/throw.
both are correct.
the former did not care if the first attack fails (expected to be countered), but keep going till you land your attack after several tries.
the later did not waste your move or energy lightly. observation first, the opponent comes, you move away and counterattack at the same time. you are doing your attack, I am doing mine.
