Action taken after firing director during regional reshuffle (9)

I believe the answer is:

reloading

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

'action taken after firing' is the definition.
I can't tell whether this defines the answer.

'director during regional reshuffle' is the wordplay.
'director' becomes 'd'.
'during' indicates putting letters inside.
'reshuffle' is an anagram indicator.
'regional' with letters rearranged gives 'reloaing'.
'd' going within 'reloaing' is 'RELOADING'.

Can you help me to learn more?

(Another definition for reloading that I've seen is " charging again".)

I've seen this clue in The Independent.
