I will assume that the amounts that you describe are the total amount that the players are putting in the pot. If so, then the answer is yes, because the last all-in bet of 5300 is more than enough to reopen the betting, Small blind 500, big blind 1000, UTG raise 2000 (total 3000) UTG+1 calls 3000, the next all-in raise to 5300 total is more than the amount required to re-open the betting to UTG+1 (the minimum to reopen the betting would have been a total of 5000). The answer is yes.

Hope I explained it correctly.
