Marx, why stop at being yotzei TT with one seder, *technically* you’re yotzei with krias shema. The ohr somayach has an amazing piece on that din, beginning of rambam hilchos TT.
Some people at certain points in their lives can’t learn, be it from emotional distress, or inability. Doesn’t mean that they can go and study something else – having a seder at night, morning, or krias shma,etc, are at times when you’re an oness. If you’re working, etc…
Once you have ample time for a seder in chol, you can have the same time learning.
