PiecewiseExpand bug?

This produces what I expect:

Product[PDF[BernoulliDistribution[p], x[i]], {i, 3}] /.
	{x[1] -> 0, x[2] -> 1, x[3] -> 1}

But this does not:

PiecewiseExpand[Product[PDF[BernoulliDistribution[p], x[i]], {i, 3}]] /.
	{x[1] -> 0, x[2] -> 1, x[3] -> 1}

It appears PiecewiseExpand does something it shouldn't here. Any thoughts?
