Filling 2 applications in lottery for 2015

As it was lottery last year, we may fall into same situation next year.

I wanted to know how much safer option will be if we file 2 applications from 2 different employers. Last year USCIS did explicitly mentioned that 2 applications from same employer will be cancelled if picked in lottery but nothing mentioned about 2 applications from 2 different employers.

If both are getting picked we can back out from either of it, as any Visa can be backed out.

U can get 2 petitions filed from diffrent employers…

U can withdraw one if both got selected… U can withdraw at any point of time till stamping…

Thanks for your responce.
