Dispatching Method of Queue in UMDF

I have virtual serial driver (umdf2) with one default queue configured for read, write and ioctl with parallel dispatching.
I had read that UMDF by default uses Device scope which means, read, write, ioctl handles will be invoked sequentially (even though parallel dispatching is give)and another will be issued when the previous IO request is be completed. Am i correct?

No, you are not correct.

WDF by default uses the parent’s sync scope… which if left unchanged is sync scope none.

I just want show the link which i have referred which says UMDF uses device scope by default.
