Not the same thing at all. There is no direct association between the 
elements so there is no way a validator or browser would know the 
difference between a missing/empty alt and an optional one - thus making 
ALL use of alt optional as far as formal validation is concerned. If you 
are implying a group can be denoted by being at the same block level or 
in the correct order in the stream (no intervening images) then I doubt 
that would work in practice.
