When he said “This whole thing made no sense to me. (Then) when I got there it made a lot of sense.”, he wasn’t saying that it made sense to stay up for 4 days starving yourself and only drinking energy drinks. In other word, was not saying that he understood the logic behind Rampage’s new diet and sleep deprivation training plan. He was not saying that he approved of the new Rampage Training Regime [RTR©] and would enthusiastically encourage other fighters to adopt it.

What I believe he was saying was that once he saw Rampage’s state of mind and what he was doing to himself he understood why Rampage went on a Rampage (a.k.a Rampage on Rampage Incident, RORI). In other words he was saying he understood that RTR is what had caused Rampage to get in trouble.

Or more formally using propositional logic…
Let d be the proposition “I, Dana White, understand what was going on with Rampage.”
Let a be the proposition “I, Dana White, understand and approve of RTR.”
Let c be the proposition “I, Dana White understand that RTR is the primary cause of RORIs.”

d → ((¬a) ˄ c)
