soemthing wierd. want to hear more opinions here

I posted here on Friday that boss indicated to me that I will be laid-off next week. then something wired happened. He called me at home to tell me "more information" that though my project is gone, my skills are appreciated. So they will create another job position with new discription so that they can hire me back. but this will take a "process" i.e. they still have to lay me off but in a few months (I guess) this new job will be posted for me to apply to. Initially I was truthfully grateful to his consideration and kindness. But now, thinking more about it, it may be just a decoy so that I do not file coomplaints to HR about unequal opportunities in this group.These are the reasons:

1. I basically know what the job descrition will be. and it is part of my current responsibility anyway. So it does not make sense to "create" a new position. They can simply not lay me off based on that responsibility of mine. So it sounds fake.
2. The HR issue is there for quite a while. I have talked with my supervier on several occasions that I was passed for many development opportunities in this group. Some of those were created by myself and given to others when they become big or on critical path. Most recently was a couple of weeks ago about unequal treatment. I was not making complaints at all, but to get a good idea what I can do or improve to make them give me a good growth opportunity. But it obviously caught the attention of all the sr managers. So I know it has become an HR issue. I think I have enough to file a formal complaint to HR and they probably know about it. It will not change anything since HR is always on management side, but will certainly become an issue for them too.
