Comment:

 Example: add this edge
 '01020000000400000000000000000034400000000000002440000000000000244000000000000024400000000000002240000000000000284000000000000024400000000000003440'
 Then split by this point '010100000000000000000022400000000000002840'
 Then validate the topology and you'll find node/endpoint mismatch.
