You do realize that soreness during exercise at high intensity suggest a build up of lactate, right? The build up of which means there's not enough oxidative enzyme in your muscles. .I thought this was discussed in another thread and it's untrue?

The article suggested that there's no such thing as lactic acid buildup because it's basically a source of energy and is gone once exercise is completed? Sorry this is off-topic but I didn't know if this was still an open-ended discussion or if a consensus was actually reached.
Yes lactate provides a source of substrate for some highly aerobic tissues, but there is a "buildup" if the work rate is high enough (i.e. above FTP/CP).
Accumulation of lactate happens when the work rate is higher than can be sustained aerobically and the body must recruit Type II fibers to maintain the level of effort. The higher the intensity of effort, the more Type II fibers recruited, and the greater the production of lactate.
Lactate is not some kind of poison, but it IS a marker that the intensity of exercise or work rate is higher than can be sustained for an extended period.
