What's up with these words, eh?

hello there = llehht oere

Voldemort’s Wrath = dloVrome s’ttarWh

This is weird, right? = sihT si riewr ,dthgi?

Just figure out what is happening to these words. = tsuJgif eru tuotahw si ppahnineot geht w essdro.

Let me know what you come up with! = teLk em wontahwuoy moc pu etiw !h

Note: It’s not just a simple fixed scramble of the letters.

Clarification: Yes it can technically be described as such, but I’m looking for something a little more sophisticated than just a fixed scramble.
