Disability under H1 and EB1

Hello All. I am in a strange situation. I have an EB1 Extraordinary Ability
I-140 filed and pending. They have given me my advance parole and work
permit docs. I expect a final result from them very late this year.
Currently I work on an H1B; not the work permit. However, due to health
complications, I am forced to take long term disability time off from my
job, for about 6 months, until October. Under Family and Medical Leave act,
my job is guaranteed only for 3 months, ie July. After that, my company
could and will hire some one else. My H1B will lapse. In the time from end
of July, when my H1 vanishes, and end of October, when I expect final result
from INS, can I stay in this country legally? I realise that if the I-140
fails, I need to leave the country in October and can stay only if it
succeeds. What is my status in that period from August to October?
