Indeed, and it's always confusing me, even after so many years I still don't know if they are all selected by default or none of them are selected by default  
Never did some searches, but today I wanted to clarify this out, thus that's not a mistake from the GIMP team, that's the way it suppose to be
I did a simple test ➤ drawing on a channel, selected one, and the draw appears on the other 3 channels, not the one I selected...



➤ Thus by selecting you are un-selecting, which means all the channels are selected by default (which makes sense) but the "selection" style LOOKS opposite as the layer style... it is not, you just un-selected a channel



BUT, if you "un-select" all, then "select" only one, the selection style now looks like the layer style...
Below un-selected all then "select" the blue channel, can draw on the blue channel and the style is as the layers' stack style...
it's because all channels are selected by default, thus the first thing we think of is they are not selected, but they all are, so we are un-selecting at FIRST when clicking on one channel the first time as my first screenshot.
If they are not selected by default we won't be able to draw or put a gradient or what's so ever, thus they are all selected.
Still truly disturbing, though, but it makes all sense



This will make even more sense to every one with GIMP 3 (2.99) because we can select ALL layers at once, and just click one to un-select it
