Tagline for True Colors: Blue Beetle's enemy, The Reach, join forces with LexCorp and Robin takes a team undercover to investigate the new alliance.

Absolutely no reason for Drake and company to travel back in time. I expect this is a public announcement of sorts - LexCorp declaring to the world about their new partnership with the Reach (note that while the Light already partnered before, LexCorp isn't the Light).
