It may well be. Though 1-2 seconds does sound a little long to me for the combined time that it takes the LSD to tighten up and for the suspension arms to take up any deflections in the bushes.
If I'm not mistaken, most moden cars don't like it if one wheel is severely under-inflated compared to the others, as it messes up with the stability control, traction control and ABS, due to the difference in wheel speed sensor readings. Did any of your warning lights appear during this incident?
