Decision Tree Classification with 0 on BOTH terminal nodes of branches?

Using t=fitctree(x,y,'MinLeaf',20) and then view(t,'Mode','Graph') to look at how the tree is working, and I see that in several cases the result at a terminal branch is for BOTH end points to be '0', or BOTH to be '1'.
How can this be? I would expect each branch to end with one '0' and one '1', never two '0' or two '1'.
Thanks!

Nothing wrong with that. A classification tree optimizes the Gini index and can split a parent node in two child nodes dominated by the same class.
