Dumb Q: should a non-systems-language dev know/read assembly?

I know C#/F# decently well, but is there any reason to actually pull out the ol textbooks and learn wtf the above is saying?

  All you could tell from this snippet is that .NET 11 eliminated 2 instructions, one of which is a branch.
  You should learn assembly anyway, but it won't make this part any more insightful.
