The intent with -t is clear. It is used only when you create a new branch. Also, you specify the remote branch you're going to create a new branch from.

"git checkout <branch>", on the other hand, will create a branch based on a remote branch, even though you neither asked for a new branch, nor did you specify any remote at all.
