Well, I meant if this wasn't the jutsu Sasuke used for interdimensional travelling (Kaguya dimensions included), then what else could it be? I'm not sure Sasuke can spam with this portal, but it was clearly said in Naruto Gaiden that overuse caused Sasuke's partial loss of doujutsu powers. However, since Sasuke opened the portal in Boruto movie and still had a nice condition for the battle, it seems like a single portal actually doesn't take a lot of power. Also, in the same movie Sasuke said he's limited to the number of people he could take through the portal.
