Nothing in the series implied that Preta Path absorption was instant. In fact, Nagato obviously didn't absorb Bee's Version 2 cloak instantly, the latter even had the time to realise his chakra is being absorbed, although it happened quite quickly I guess. The same case with Jiraya's Choodama Rasengan. Also, while Nagato is "gording" himself, it'd leave him open and vunerable, which would give the chance for his enemies to counterattack.
