I've just went through all 6 betas, and the Cut icon does not add a cut to the timeline in any of them.
In Beta 1, it does nothing. It's busted.
Look at the Cut icon in relation to the other 2 icons in that group, which are Dissolve and Smooth Cut. These are for transitions between clips. When you click the Dissolve or Smooth Cut icon, it will affect the clip boundary closest to the playhead. And it will convert that clip boundary to a dissolve or smooth cut.
The Cut icon is to convert either of those back to a ... cut.
And this is what it does in b2 through b6.
