it's not crazy talk 
It's a knowledge of the mechanics.
The "you can't heal me" debuff lasts 8 seconds. Monks have a 5 second cooldown on their heals. When a Monk's heal cooldown drops, it does an iteration of all the units in range, starting with the demigods and then doing themselves and then doing the rest of the units around them starting with whatever is closest (this tends to be the other monk).
The second it finds a unit that would not be "overhealed" (basically at a % HP where the healing will be wasted because it's super-close to 100%), then it performs the heal on the unit, attaches a debuffed to the healed unit and puts the heal onto cooldown.
Let's say that you have 2 monks, and you're against a Level 1 TB with Rain of Ice. TB does RoI on you and your monks. You'll usually instantly be healed at this point assuming you haven't taken any damage. This attaches the 8 second debuff to you. Then, one monk will heal themselves. 5 seconds pass (heal cooldown).
The monk that didn't heal himself will heal himself (doesn't have the 8 second debuff). The last monk will look around for units to heal. If it can find a minotaur to heal, it will. Otherwise it'll just idle for 5 seconds and do nothing (yes, put on cooldown again). Then 3 seconds pass and your debuff expires. However, both monks are on cooldown for another 2 seconds.
The only way to actually get monks to heal you every 8 seconds is if they are staggered from when they were summoned (eg, you lose just one monk and resummon just that monk and it pulses at a different frequency than your other monk).
