Hi , can anyone explain this?

All of these 1.01 vs. 1000 are cases where, effectively, you can't bet.
If you back - you only get 1 cent back, and if you lay - you need to offer the bettor 1000:1 odds (against you).
You can provide liqudiity normally, but no one else is.

Its a glitch. Happens occasionally when Betfair was off due to technical error and they coming back. Dont know what about abovementioned situation but who cares, it doesnt happen often any its not anything would influence anyone.

ok, you're right, but that I've had this situation for the past three days at about half of the live matches. So it can't be a glitch
