Except that he doesn’t have bijuu chakra in this situation, i believe. And regardless, it’s not the same thing. It’s not a matter of speed, it’s a matter of sensing. Regardless how fast Nagato is, he can’t react faster physically than with shinra tensei.Shinra tensei is a hell lot faster than Nagato ever was. If Nagato is aware that amaterasu is coming, reppeling it with shinra tensei is a hell lot faster way than dodging it with speed. And since Nagato’s sensing are the same regardless if he is mobile or crippled, he shouldn’t be able to reaxt in time, since he didn’t against Itachi.

Now, Nagato was an edo at the time and EDO’s are slightly weaker than the alive version, so the situation is debatable.
