It does if you look at it that way. But it doesn't spoil "Naruto" for you - it will just move the point where you don't know how it continues a bit further ahead.

If you only watch tha nime your weekly question is:
what happens next? [anime]

If you read manga and watch the anime you have:
what happens next? [manga]
how did they animate that? [anime]
what did they add? [anime]

And, afterall, the manga is from Kishimoto himself and much better than the anime.
