I suspect the original circuit is a series resonate circuit at the
ripple frequency.
This kind of circuit has a specific name that escapes me at the moment.
(other than a low pass filter)
The "minimize arc current" is an important aspect of this clever
design, it is
not arc suppression. This is more important for some tube construction
than
others.
