Although, Exclusive = true at the activity makes sequential execution by the same thread , in that case parallel join gateway should be marked as asyncBefore=true for synchronizing the state.

I have updated this in above post as,

To acheive concurrency, set asyncBefore=true && Exclusive=false to both of the parallel tasks and the parallel join gateway should be marked as asyncBefore=true & Exclusive = true for synchronizing the state.
