Based on my own experience I have to respectfully disagree with this statement, at least as it applies to DWC hydro systems.

As long as the reservoir is big enough, you should be able to remove any males or unwanted plants fairly easily as long as you do it before the roots become too tangled (the amount of time depends on the size of the res). The trick is to actually lift the entire plant, roots and all out of the system. Use your fingers to comb through the root mass and help untangle it from the other plant(s). If you look at my current grow log, you'll see the six plant, single res system I use. I've removed plants from it on every single grow I've done - a couple of times after the plants were pretty good sized. If you look at this picture you can see how big they were last grow, and I removed three plants without any problems at all.

That said, the general rule of thumb for a DWC seems to be 3 gallons per plant. Putting two plants in a single 5 gallon bucket might be a bad idea, unless you're going to flower really early to keep the plants small. If you're growing from seed, that wouldn't be possible since it can take a couple of weeks of 12/12 for them to show sex. In that time they would probably have grown to large to safely separate.
