block of redundant code

[firnprotocol]

it seems that the entire block of code

BokkyPooBahsRedBlackTreeLibrary/contracts/BokkyPooBahsRedBlackTreeLibrary.sol

Lines 126 to 136 in a8e9864

	uint yParent = self.nodes[cursor].parent;
	self.nodes[probe].parent = yParent;
	if (yParent != EMPTY) {
	if (cursor == self.nodes[yParent].left) {
	self.nodes[yParent].left = probe;
	} else {
	self.nodes[yParent].right = probe;
	}
	} else {
	self.root = probe;
	}

could be replaced by the the single call replaceParent(probe, cursor), with identical semantics. am i missing something?
