Hmm I've been Lackeying a low level MM friend of mine for the past few days, He's been in and out of range plenty of time and hasn't mentioned his minnions dropping dead nor have I noticed. I'm a brute btw. I'll try this tonight if I get time and see what happens.
It does sounds alittle the wrong way around. I've seen it the correct way around - ie loosing higher level pets when your out of lackey range.

Did they drop dead or just lose levels?
It was definately only happening when he got back in range though 
If you drop or gain Combat Level (more than +1 I believe) then yes your henchmen will keel over after a period of time.
It's to stop you having high-level henchmen in a low level mission/area and hence by design. Same thing happens with Controllers/Dominators and their pets.
If you are Lackeyed/Malefactored stay close!
It wasnt after any specific amount of time it was as soon as I moved back into lackey range.
Last night I was grouped with my bf to help him with some AV and Hero missions he couldnt solo. We got into the mission and I summoned my minions then he went off to clear up the minions while I went through my labourious buffing and setting up routine
- he's a brute, brute smash, brute not stand still and wait around 
So he went on his merry way clearing out all the minions and I went through my buffing cycle, rested my end then set off to find him, as soon as I got back into lackey range all my pets dropped dead.
We tried this 3 times, if he went out of range my pets would drop dead on the spot when he came back into range.
Anyone else had this problem?
If this is intended then it seems rather [censored] backwards, surely if they have to drop dead it should happen when he gets out of range, not when he comes back.
