biff44 has given the most likely explanation. As an additional remark, it's also very likely a later correction of a design flaw, cause this kind of filigree hand-soldering would be strictly avoided in a design, at least in the US or europe.
Rod core inductors are generally interesting for higher current supply filtering and EMI suppression purposes. They are showing however self-resonance in the 100 MHz range. Typically a series circuit with an inductor or ferrite bead effective at higher frequencies would be used to overcome this problem.
Although the partial capacitances can be predicted with EM simulators rather accurately, a resonance frequency respectively impedance measurement would be a better method to characterize the part, I think.
