If you're hired to port a system to a new platform, it may not be a bad idea to spend time working on it on the current platform(s). Especially since iOS <-> Android conversions aren't always straightforward. If they developed it in Objective-C using Apple's supplied libraries for GUI, network IO, etc, they'll be doing less porting and more rewriting. From then on they'll be maintaining two code bases, not just a fork that replaces certain segments with Android specific patches.
