You need not be diffident regarding acceptance of resignation in June while you were relieved from 31st August. This could be explained as the effect of notice period. Though you gave resignation on 19th June and it was accepted on 19th itself but due to notice period, your relieving is from 31st August. This is a widely accepted practice.
From the brief description, it is surmised that you were working in sales/distribution and the accident occured while you were on duty. But such nature of work is not covered under Employee Compensation Act 1923 and so you cannot get the benefit of that Act.

So as per above statement if my resignation has been accepted and i was relieved then the agreed salary till 31st of august should get in one go in full and final. But they said you will get it on monthly basis and in between if you will get some job we will stop paying you.
So if i would join some new company and will give this letter and later on when they will ask for relieving letter which says relieved on 31st of August would create a doubt in new employer mind.
Hope i am able to make you understand about the scenario.
