Not sure why they want to know, but they do. But it is not an issue
They want to know because it can be an issue. If you are residing in another country during that time, they can pull your oath out. Or if you have gone over your number of days in the US since your Green Card, they can deny your oath as well.
Remember even during that time between the interview and the Oath still counts towards your citizenship requirements. You and not a US citizen and if you were on the border before with the number of days getting close to exceeding the limit outside the US, then this time could very well push you over the limit and your Oath will be denied.
Now if you have maintained US residency though that period and you don't go over with the days, then yes you will be fine...
