This assumes he had enough control over his Susanoo. It's possible that he could barely hold the technique together and had to fire Indra's Arrow or lose control over the absorbed energy entirely. It's also possible the strength of Naruto's attack was too great to absorb (again: risking losing control entirely) or that he had little time to react, couldnt abort the formation of Indra's Arrow and switch to Preta and so simply reacted with the Arrow.

Lastly, it could simply be a matter of pride, since he wanted to match Naruto's strength.
