please, about grammar question

[caijq]

I read this sentence in a vocabulary book. So I think grammar definitely right.
But I'm confused about "absolute loyalty" position.
let's see the sentence.
"But what perhaps most astonishing about Mr. Jobs was the absolute loyalty he managed to inspire in customers."
I only can understand the sentence form is "But what perhaps most astonishing about Mr. Jobs managed to inspire in customers absolute loyalty."
So what about the original sentence gramma, which teacher can explain my question. Thanks a lot.
HAPPY CHINESE NEW YEAR

HAPPY CHINESE NEW YEAR

The sentence is badly formed. It should be:

But what WAS perhaps most astonishing about Mr. Jobs was the absolute loyalty he managed to inspire in customers.

Or perhaps more idiomatically:

But perhaps the most astonishing thing about Mr. Jobs was the absolute loyalty (that) he inspired in customers.
