Well sort of, Peter.
But properly recorded channels of audio from a single mic are phase coherent. That means the rises and falls of the waveform happen at exactly the same time on both channels.
More likely, what's going on is that the connectors are not wired properly to bridge a mono mic to two inputs. To do that, the #2 pin of the female XLR needs to be connected to both the tip and the ring of the 1/8" TRS plug that goes into the camera. That way, both inputs get fed the same signal properly.
You may also have another issue. Some camcorders mic input circuitry generates a small voltage that is used to power some mics. This bias voltage can work against you with some mics, causing distorted audio. Trew makes cables for these inputs that block the DC bias voltage. They make a two channel rig for when you want to use two mics, each to a separate track,

and a mono rig for when you want to send the audio from one mic to both channels.
