You "could" if the horizontal parts of the letters are the same width as the vertical parts, but it will take a little work. Basically you turn these two parts into separate rectangles, and v-carve each one. That will give you the sharp corner you desire.
The reason it creates that curve is because the VCarve will go to max depth so that the edges of the bit touch the outline. Because that gets wider as you approach a corner it will create that "round" where it's actually going a little deeper as well.
