It seems to me that the problem with this match was that one disqualification was given after another, the second of which potentially would not have happened if the first disqualification were effected immediately.
The fairest solution I can think of is that in the case of multiple DQ's for seperate incidents (in elims only), if they occur seperately (that is, at clearly different times and events), only the first one counts.
1. In the first 20 seconds, Redateam 1 tips Bluateam 1's bot in an aggressive move.
2. Ref makes a notation of the DQ-warranting offense, but doesn't signal it.
3. In the last 20 seconds, Bluateam 2 tips Redateam 2 in an aggressive move.
4. Ref makes a notation of the DQ offense.
5. Refs deliberate, and decide that the first offense was DQ-worthy, and the rest of the game is nullified.

It's not perfect, but it's better than giving a team the chance to rise from the grave after getting DQ'd without a disable. Of course, disabling them in the first place would also do the trick. If the offense is blatant enough to warrant a DQ later, it can probably handle a disable earlier.
