QlikView Script Query with Multiple Load statements

[Ahsan1]

Assuming the case below

Table X:

Load* 
This load might include some new fields formation from the existing fields

Load*

This load might also include creation of some new fields from the existing fields. 
Resident Table Y

Could someone explain why are multiple load statements excueucted here ?
What could be the purpose behind multiple load statements in above mentioned case ?

[edwin]

are you referring to preceeding load?  where there are two or more load statements for a single source?
