Think that michilo is talking about report's pins, not road segments.
As you probably know, colorcoded traffic is little late. So if first Wazer report's standstill, you have pin displayed seconds after, but it takes up to 5-10 minutes to get road colored (also works the other way, color disappears with delay). If the pin was red, you would notice standstill jam, if heading that direction.
if it looks strange, it's my phone's fault
