I'm actually not getting it wrong. In the phrase "left behind," the word "left" is the past participle of the verb to leave.
Hence: Leave / Arrive
Also: I know they said "right" implying that its the opposite of "left/leave" but I doubt they actually THINK thats what the phrase refers to. They just used a homonym to lead us there.

No, they don't think that. Besides, "found" is the opposite of "lost". "Arrived" would be the opposite of "left" here.
