Does this mean we can reasonably expect Reus to join Liverpool?
No u cant expect that. It doesnt matter what coach or club wants to sign Reus, Dortmund r not interested in selling players, that r very important and have a contract longer than one year. In addidtion to that, the relationship between Reus and Klopp havent been that close to suggest, that Reus would follow him to Liverpool. Hummels and Gündogan have just a year left on their contract, so IMO there is a high chance of them moving to another clubs next summer (Hummels I predict EPL and there prob United and Gündogan I predict Barca), so Dortmund ll be reluctant to sell the other star player too. I could see him going for Subotic though, as he has been really close with Klopp, isnt a starter anymore and always wanted to play in England. He ll focus on promising youngsters and players from German, he ll maybe be interested in and with chances to get, could be e.g. Bellarabi, Herrmann, Brandt, Süle and Volland. He has been a fan of Tielemans too.
