'please go before me' is the definition.
I know nothing about this answer so I cannot tell whether it can be defined by this definition.

'in pursuit of solver' is the wordplay.
'in pursuit of' becomes 'after' (as in chasing after someone).
'solver' becomes 'you' (the person solving the clue!).
'after'+'you'='AFTER YOU'

Can you help me to learn more?

(Other definitions for after you that I've seen before include "Yielding statement" , "I'll follow" .)

I've seen this clue in The Irish Times.
