Why are Felicity, Cisco, and Caitlin re-introduced to each other in The Flash: Going Rogue?

When Barry was struck by lightning and went into a coma, Felicity constantly traveled to Central City to visit him at S.T.A.R. labs, where she met Wells, Cisco and Cailtin. However, in the Going Rogue episode of The Flash, Barry introduces her to Wells, Cisco, and Caitlin, saying, "This is Felicity Smoak, she works with the Arrow". Why would she need to be re-introduced when she's already spent a substantial amount of time with them from visiting Barry and from their interaction in season 2 of Arrow?
