俱舍論記 10.174

10.174

「此目中有至暫時起故」者，答。經說中有，異名五種，求生是即五中一稱，明知前經所說求生即目中有。餘文可知。

Regarding 'This designates the intermediate existence [...] arising only temporarily': This is the answer. The sūtras state that the intermediate existence has five synonyms; 'seeking rebirth' is one designation among the five. Thus it is known that 'seeking rebirth' spoken of in the preceding sūtra precisely designates the intermediate existence. The rest of the text is understandable.
