Fine points that the reliability of the above account is at times difficult to determine because the lack of further sources. There are some obvious inaccuracies at times but the basics of the story could be true. A succession crisis in Zachlumia with the existence of rival heirs would be quite plausible. Nemanjić would have reason to get involved. His ongoing rivalry with his brother in the late 1190s would require him to secure control over Zachlumia, in order to prevent Vukan from claiming control for himself. However his activities in the area are otherwise unrecorded. His motivation for backing Andrew against Peter is also unclear. Either of the two could serve as rulers of a puppet state. Installing Radoslav as ruler of eastern Zachlumia would be a way to secure tighter control of the region.
