BiTgte_Blend for creating fillets?

In Draw the command trollingball uses BiTgte_Blend. But it is not documented in the Draw User's guide.
Is it another way to create fillets instead of using BRepFilletAPI_MakeFillet?
There are no references from other OCC classes to it (except from Draw). Is it deprecated code?
Does somebody use it?

BiTgte_Blend and BRepFilletAPI_MakeFillet both create a fillet.

BiTgte_Blend requires that two surfaces intersect / penetrate each other. They should not have a common boundary edge.
BRepFilletAPI_MakeFillet, on the other hand, requires that they have a common boundary edge.

Draw-Script for tests with BiTgte_Blend:
restore face1.brep f1
restore face2.brep f2
shape qq C
add f1 qq
add f2 qq
rollingball r qq 15 @ f1 f2
