First, the speech is about INTERRUPT SERVICE ROUTINES names. Not about of 
electrical signals or human readable designations.
Let us look ATtiny2313 datasheet (next page after Table 21).
ISR names differ from specified above:
    ...
    rjmp   INT0
    ...
    rjmp   TIM1_CAPT
    ...
    rjmp   TIM1_OVF

Certainly, it would be good to use names from Atmel's datasheets from the 
first. But, unfortunately, Atmel is very inaccurate in ISR's names.
Identical subroutines have different names for different chips (for example,
EE_RDY in AT90S4433 and EE_READY in ATtiny2313). Sometimes the name clashes 
with other identificators (INT0 above).
