Old Bike vs New Bike

We have had some perpetual construction in our area, and while walking just now, I noticed that the spray-painted tags for bike lanes have changed.  Or they are still evolving, or whatever is happening.  There is one traffic logo with a little person with a helmet (but no bike), and another with just a bike (no rider).  And in the new paint jobs of just the past year, in the same development, they used both logos.  Here they are just 20 feet from each other.

Is the no-rider logo replacing the no-bike logo because someone got bent out of shape about the rider not looking male enough or female enough or neutral enough?  So now we have to watch out for bikes with invisible riders because we can't look at people anymore.  Maybe that logo didn't look "bicycle" enough.

Or maybe after years of bike logos without riders, someone finally noticed and felt that a rider was needed.  But now it's a mime pretending to ride some tires instead of an actual bike with rider.  It's a mystery.  I would expect national standards or even international standards for traffic markings.
