I've been inactive longer than you and I got a sheparding call shortly before the Memorial. I wondered what was up because they were pretty damn insistent on meeting. I tried to juke and jive out of it but they finally pinned me down on a time.
I figured it was the new "put up or get out" pressure we had heard rumored about, but it was nothing like that. They were just following the spirit and letter of Mother's rules of visiting the inactive and "encouraging" them.
I kinda got worked up about it, ready to do battle but in the end it was nothing special. They bullshitted a bit, I avoided answering questions and they wished me a fond farewell while inviting me to the KH for the Memorial.
So, like's been said already, it depends on what their motive is. If they've heard some disturbing news about you, then they be in a preliminary "investigation". Otherwise they're just doing an inactive sheparding call.
If you don't care about trying to remain "faded" for family sake you can just tell you don't need their assistance. They'll probably talk shit about you when they leave, but there's not much they can do without a confession or two witnesses. If you're trying to stay under the radar, you could meet with them, but just don't let them get you talking too much. Keep it short and sweet. You can disarm them with kindness and friendliness.
