Birth Certificate Queries

This is a copy of my late mother's birth certificate.

Maybe I am unduly suspicious, but why would someone ask for a clerical error to be corrected 10 months after the registration ?

And does anyone have any idea why a copy might have been requested when she was 2 and half?

It could just be that the original was lost, but would a copy have been needed if she was going to be taken abroad? (I thought she wasn't taken abroad until some years later)

Thank you
