Funny English – Disbarred means not allowed to practice, does ‘Barred’ means allowed to practice? – Lawyer terms

I encounter this funny meaning of disbarred from a local newspaper site ( concerning two lawyer brothers were disbarred from practice because of dishonest conduct. What bug me is, I’m usually accustom with the word ‘barred’ to mean ‘prevented’, ‘not allowed’ and disbarred should mean the opposite like : “Yay, they accepted my appeal, I’m finally disbarred!!” lol. Okay, to be frank a friend of mind did told me in law terms, ‘disbarred’ means the expulsion/removal from the Bar Council.

But does that means being ‘barred’ is a good thing for a lawyer? :p
