So, if I understand correctly from above, this would be a false double foul, a personal followed by a technical.

You don't understand correctly. That's completely wrong by rule. Specifically rule 4-19-8 which says "A double personal foul is a situation in which two opponents commit personal fouls against each other at APPROXIMATELY the same time." That includes immediate retaliation.
