GEPIK as backup

I emailed the recruiter about GEPIK.  I said I want to apply in case EPIK doesn't work out.  I didn't really understand her response.  She said she can promise me placement through GEPIK if I fail the EPIK interview?  promise me?  Are they desperate?  I wanted to apply through GEPIK not so much cause I am worried I will fail the EPIK interview (I am a little worried, but not too much) but because I am worried I will get put in some place I don't want to live.  Like anywhere other than Busan or Incheon.  I'll go almost anywhere in the GEPIK area, but not anywhere in the EPIK area.
