It mentions this under the "Force Exile" Talent tree and I was wondering exactly what it was.

I'd imagine it refers to a character's ability to recover Strain by "taking a breather" as discussed on page 144 of the Beta rulebook, under Recovering From Strain.

That the talent text on page 89 says "when recovering Strain at the end of an encounter," so it's most likely a case of the table having outdated information from an early point in EotE's pre-Beta development cycle.
