1. No one ever said foreigner workers can get residency at all. The case is simply arguing the Basic Law gives them the right. But no one knows until the trial. Beside, foreign workers are subject to immigration control. So it is a doubt that how they can meet the "ordinary residing" requirement.

2. No one ever said that.
3. No.
4. They are in different system. Simply saying, other places have better systems in handling these issues.
