Does anyone know the reason that Bobby Reid was reinvented as Bobby Decordova-Reid on Saturday?

I was struggling to read the back of his shirt (a lot of letters) but the club match report used the 'new' name too.

I assume the 'Decordova' is his mother's name (or maybe his wife's - I have seen some double-barrelled names appear after marriage when both partners adopt both names?).

Whatever, it looks like Bobby has decided to adopt a new identity with us to mark his break from his Bristol past.
