I stumbled across the following narrative in Guardian:
The political implications are potentially far-ranging. Anxious to avoid personal blame for twin health and economic disasters, Putin has shifted responsibility for managing the crisis to the regions, which have effectively been left to fend for themselves. Wealthy businessmen – the so-called oligarchs – have stepped into the breach. In such ways does a leader’s power erode and slip away.
As I understand, there seems to be a myriad of reasons, rules or conventions for the inversion of a sentence just like that one in bold.
Would you please explain why this example follows the inverted structure? If you could also lay out further examples to illustrate your explanation, a thing you normally do, I would be grateful.
Many thanks in advance.
