Of course. Name conflicts are always a potential problem. But it is silly to expect me to know every possible toolbox, and every existing function name in every toolbox I do not own.
MATLAB does NOT have a problem with me naming a function something even though they have already used that name in some toolbox I've never seen or intend to use. That would be insane.
In fact, I can happily name a function with the same name as an existing function, as long as I am cognizant of what I've done, and take care that it does not cause a problem. Yes, this is dangerous, and even often foolish, but still possible.
