Although I never got an explanation, their managers were probably selling their employees to multiple projects. I've heard that this happens from people working there. Offshore developers from a body-shopping company who are shopped to multiple customers is common. I've seen it happen multiple times in different countries. I have over a decade of experience trying to make off-shore development work with several off-shoring companies, one of which was a wholly owned subsidiary (to avoid the various overbilling strategies). I've never been convinced it is worth it overall. The semi-irrational insistence on off-shoring was actually one of the primary reasons I quit my last job.
