Here "name" represents "authority." This means Paul did not baptize others because they may claim that they became Paul's disciples. This can be stated in active form. Alternate translation: "For some of you might have claimed that I baptized you to make you my disciples" (See: [[rc://en/ta/man/jit/figs-metonymy]] and [[rc://en/ta/man/jit/figs-activepassive]])
