Nope, it's the other way. Crawl on vertical edges (horizontal transitions) like that vertical blue pole comes from a notch filter.

Crawl on horizontal edges comes from a comb filter, especially one that does not have a sophisticated circuit to detect the crawl condition and switch on a notch filter when necessary on that scan line.
