Independent Assortment vs. Segregation

[WiseIdiot]

what's the difference?
To my understanding, independent assortment is each allele going separately into each offspring when doing the Punnet square thingy and not affecting the placement of other alleles of other gametes.
WHEREAS
Segregation is the formation of unique gametes from the genotype of the parents, each gamete not affecting the other.

However, aren't these definitions almost identical?
