Because the iodine is liberated, hence it is called as iodometric titration.
hypo solution used in iodometric titration is sodiumthiosulphate. Its N\10 normality of Na2S2O3.
excess KI
No, they are not the same, but 1 is part of 2.Iodometric titration is just one of the (larger) group (or class) of oxidimetric titrations, which in turn is part of the much (larger) group (or class) of volumetric analysis method.

drift means gram eqv. of water removed by K.F. in Iodometric titration
Iodometric titration is synonymous with redox titration method. Iodine is a universal laboratory reagent because it reacts directly with an array of organic and inorganic substances. Since iodometric titration is a form of redox or oxidation-reduction reaction, it can accurately measure the amount of oxidizing or reducing agents in a chemical reaction. Also, it can be reversed to either direction in an iodine/iodide reaction.
Iodometry, also known as iodometric titration, is a method of volumetric chemical analysis, a redox titration where the appearance or disappearance of elementary iodine indicates the end point.
A thiosulfate titration is mostly carried out to determine the amount of iodine present in the solution. In these reactions, thiosulfate ion acts as the reducing agent. This types titrations are often called as 'iodometric titrations'.
It is used as indicator for the endpoint of a Iodometric (redox) titration: it gives a bluish grey to black color with very minute excess of Iodine-iodide ions (I3-)
Starch is not used in order to do this. This is because starch is able to form a complex along with the iodine and this is the indicator.
In this titration iodine is liberated ....Added:... from (excess of) iodide by an oxidant. The Iodine is then titrated with thio (di-sodium thio-sulfate) and starch as indicator added just before the expected equivalence point.
