This counter tracks the total number of alternate-route query packets received from all neighbors in this autonomous system. Receiving frequent queries means neighboring routers are losing routes and asking this router if it has an alternate path, so a high rate here, even if this router's own links are fine, indicates instability elsewhere in the EIGRP topology that this router is being asked to help resolve. If a hub router's received-query count spikes whenever a particular spoke's link flaps, that pattern confirms the spoke's instability is propagating query traffic to the hub even though the hub's own connectivity never changed.
