that would be normal for a standard differential. By way of the spyder gears inside of the diff, there will only be 1 driving wheel at a given time.
Only posi-trac diffs and maybe LSD diffs(depending on friction coefficients) would have both wheel turning at the same time.
I'd say you are just fine!
Have a lot of fun with ur new ride & welcome to the werkz
