I think it's safe to assume anywhere that sus == sus4.
Sus2 is different.

The 'sus' is short for 'suspended' and what it means is that, instead of resolving to a stable triad, it's deliberately held away from the triad. We expected the chord to resolve, but it doesn't yet ... it keeps us waiting, it keeps us "in suspense".

Usually sus4 goes on to resolve to the Major chord and sus2 goes on to resolve to the minor chord, but I think one can't rely on that, Sometimes it's a tease and the chord progression goes somewhere else instead.
