Not 'mangled', it's easier for people to remember "product over sum" or "product divided by sum" than "reciprocal of 1/R1+1/R2+1/R3...".

If the result is the same, why is this a problem?

It's called "first principles". The derived calculation for two loads doesn't show how it works, only applies to two loads, kind of a "teach a man to fish..." situation.
