Following all my questions above, you may have already come to a picture, so I hope you will not be surprised too much by my comments below.
When you were outside the US in 03/2008, you were bearing two valid H-1b approval notices, which gave you option to choose which one you are going to work with.
By filing DS-156/157, together with supporting I-129/I-797 relevant to your previous employer, you conveyed a message to VO that you chose to go back to previous sponsor.
Your such choice was further confirmed at the admission. BTW, CBP was found no mistake on your case so far.
However, you did work for current employer after admission, which left you being OOS. And, you have stayed beyond I-94 expiration, which left you to be subject to 10-year bar.

Hence, it would be really challenging to request "Nunc Pro Tunc" from USCIS on your present H-1b transferring. If the case is represented, talk to the attorney. All you can do now is to cross your fingers.
