Take a look at the manual of ISP1160, paragraph "9.5 HC > Operational Model" on page 29. In the 3rd and 4th paragraphs, we read > that SOFITLint is issued first, followed by ATLint.

It depends on how the interrupt handler is implemented. Lothar has done it so that processing of ED/TD lists is triggered by SOFInt and processing of finished (or half-finished) transfers is triggered by ATLInt. These are two clearly separated tasks and I think that Lothar's choice for implementation is logical.
