Yeah, it's the same one, he's after the Cache of Glabados, which he tells Vaan in a note to come check out at the end of FFXII. Vaan and Penelo arrive there at the beginning of Revenant Wings.

An interesting note is that the Zodiac Stones are referenced also (or all-out renamed) as "the Auracite" which are the stones used for summoning espers (the 12 scions in addition to the "yarhi" (monsters)). This reference, in addition to Balthier, connects XII's eastern region Ivalice (Galtea) with FFT's western region (Ikoku).
