Yes, that's true, i forgot about that. You can "put it back" within that very short time-frame, once per year, and only if the Roth IRA in question hasn't previously been involved in a rollover in the past 12 months.

If we're getting into the details of this, OP could also make a qualified withdrawal if he becomes disabled, if he's buying his first home, or if he dies and his beneficiary wants to make a withdrawal.
