-(으)ㄴ 후에
-(eu)n hue
Same line, other side: -(으)ㄴ 후에
The picture Marking a dot on the line of time and putting your finger on the space to the right of it. The door has already shut. -(으)ㄴ 후에 is the space right of the point, -기 전에 the space left of it — and the form in front differs too: 먹기 전에 but 먹은 후에.

All of it in one picture
-(으)ㄴ 후에 marks a point on the same line of time and this time puts your finger to its right. Only past the meal point does the pill go down; only past the end of work does the call get made; only past the hand-washing point do you touch the thing. In the empty space after the meeting closes you talk; at the far right end of a three-year stretch you quit. So the first event is already over — you are pointing past a mark that has been made, which is why the verb comes in its completed form: 먹은 후에, never 먹기 후에.
