That is not correct.
If 485 is denied and you don't have any other basis to stay here (ie., valid non immigrant status); then clock starts ticking on the 180 days unlawful presence from the date of denial (note: you are illegal once the 485 gets denied). Filing an appeal or motion to reopen without any other status doesn't give one a right to stay in usa. (this has been reinforced many times by uscis in various memos/guidance).
I fully agree with unitednations. Filing appeal does not give you a legal status to remain in US while waiting for decision.
My attorney suggested following scenario in case of denial:
filing application for change of the status to B-1, which is non-immigrant 'business' visa, and ask 6 months and explain that you got denied and plan to leave the country but need this time to take care about your business: sell car, sell house (if you have one), take care of bank account, finish school year for kid, etc.; note that it should be B-1 'business' and not B-2 'tourist', you should not ask tourist visa to look around US, ask bor 'business'. trick was, application should reach INS before or in same day as denial, so you are at this moment in legal status, which is impossible of course, so the advice was to prepare this papers and be ready to date them and fedex to INS.
According to my attorney, you are legal in US after filing such application since the date INS receives it, while waiting for decision, even if they deny your B-1, you will be legal until you get denial (processing may take several months) and then have to leave 'immediately' which I think may mean 10 days or so.
I am not sure if this works for I-485 denial, my case was I had I-140 denial and I was afraid my H-1 will be dead soon (company run out of money) so I planned this for change H-1 to B-1 in case my H-1 will collapse. Fortunately I found another job and tansferred my H-1 and then appeal for I-140 was approved and I filed I-485 which was also approved recently.
But I did what my attorney suggested, filled all paperwork for my family for B-1 application and had them ready....
