This isn't true. Chrome itself proves this when loading a site affected by wave 2 of the distrust:
"The SSL certificate used to load resources from https://(domain) will be distrusted in M70. Once distrusted, users will be prevented from loading these resources. See https://g.co/chrome/symantecpkicerts for more information."
Everything was being done in 2 waves. First wave was Chrome 66, second wave is Chrome 70. See Google's link above for the specifics.
Source: Chrome's own warnings and that I work for a business that deals heavily in SSL sales.
