My guess would be they were just trying for a bright clear yellow. I have
a chart that shows the different shades of yellow and red glass that have
been made over the last several hundred years. The earlier shades of yellow
were all a little dull -- starting out with a fairly golden-yellow and then
moving to a slightly brighter shade. Yellow glass made with uranium is a
nice bright clear shade. (It approaches what we'd now call a neon yellow.)
Uranium was just another mineral in the pre-atomic age. And the danger may
not have been apparent -- remember, the ladies who used to paint the radium
on glow-in-the-dark watch dials pointed their brushes with their tongues at
first.
