Well yes and no. Once you've already hit quads once the odds of getting quads a second time are just the odds of getting quads. But if you're just asking the probability to get quads twice in a row on any particular pair of hands then yes it would be pretty high.
I actually had quads twice in a row a few weeks back as well... might have been on 2 seperate tables though.

I recently got dealt AA 3 times in a row in a tourney, now that's pretty unusual. The more unusual bit was that all 3 won and all 3 got me a bounty!
