It's an interesting argument; however I am a little dissuaded by the fact that half of the support for the claims of similar syntax between Norwegian and English (split infinitives and placing a preposition at the end of a sentence) are generally considered poor grammar in English.
They're considered "poor grammar" for historical reasons (mainly because they're impossible in Latin), not because they are not understood (compare to "I the dog kick" which is ungrammatical in a much more rigorous sense). From a linguistic standpoint what's interesting is what is understood and what isn't, not what is the most proper.
Those protests were popularized by grammarians who learned grammar thru a Latin lens, so, to them, being used to the Latin grammar, this construct in English looked incorrect. From a Germanic language context, though, it's perfectly normal.
