Well, the O2 was probably all purged through fermentation and degassing if it was done in a carboy, so that's fine. The lees may have just added a little lees character (not too much since it wasn't stirred I'd imagine) which some people like, and the fruit... well I'd expect something to go sideways in that amount of time with the fruit, but apparently the alcohol did it's job and kept it from spoiling.
EDIT: and did yours make it to 10 months old?
