vice versa

I'm a little stuck... Click here to teach me more about this clue!

'depravity while vicar turned the opposite way' is the definition.
I can't tell whether this defines the answer.

'depravity while vicar turned' is the wordplay.
'depravity' becomes 'vice' (I've seen this before).
'while' becomes 'as' (eg 'while I walked' means 'as I walked').
'vicar' becomes 'rev' (reverend).
'turned' says the letters should be written backwards.
'as'+'rev'='asrev'
'asrev' reversed gives 'versa'.
'vice'+'versa'='VICE VERSA'

Can you help me to learn more?

(Other definitions for vice versa that I've seen before include "film" , "Revise a VC? (anag)" , "The opposite (also applies)" , "otherwise" , "With the order reversed" .)
