Analog multimeters can still show false positives, but usually in the form of weird ghost voltages because they are Hi-Z meters. They have a high impedance designed to keep influence on the circuit being measured as low as possible. This is great for electronics with low voltages where a current flowing through the meter could cause a significant voltage drop), and to some extent for line voltage too (where a current flowing through the meter from hot to ground could trip a GFI) but on the other hand those meters can show ghost voltages caused by induction or capacitive coupling that would vanish if a current flowed through the Lo-Z meter. Unless I want to know the exact voltage +/- a few volts I have been able to work quite nicely with just a Lo-Z meter with a bunch of neon lamps or LEDs indicating different voltage levels (12, 24, 48, 120, 230, 400V) that allows to switch off the load resistor for Hi-Z measuring.
