Why LED don't fry at (limited) potential difference of ~3v? We don't limit the current but still LED is fine.
As I previously said you are also right one way. When two parameters are directly proportional to each other at some constant 'K' .. limiting any one will automatically limit the other.
Its same as the half filled glass of water; one person says that its half filled while the other person says it half empty. Both are right.
