[Grammar] suggest someone do something

[GoesStation]

But would you explain these two sentences: in the same, (which is) very clear: "Your shoes are blue, as are mine.
You are happy, as am I.", especially their difference from as is in the original post which you have explained in #22?

I can see why this construction is hard to grasp. It's hard to explain, too!

This is one of the cases where we invert the subject and verb in a declarative sentence. In Your shoes are blue, as are mine, the second clause is a more elegant way to say "My shoes are blue, too," or "So are mine." (The latter demonstrates a much more common case of subject-verb inversion.)
