Why can I not align the denominator later on? (it gives me completely different values)
I thought I already got this down pat, but I guess not. Can someone point me to where my knowledge gap is, and where I need to brush up?

They are actually the same! When you expand the top expression, you should get the bottom one. Note the bottom expression is under the category Alternate forms, so they are all the same, just written in different forms.
