Thanks for the comment! It'd definitely be interesting to see this same analysis for annual rides to see how many people fall into a similar category as you.

To quickly clarify: The growth chart only includes customers who paid for an Uber ride in that month, so any customers riding 0 times are not counted. The "Domestic Customers by Monthly Rides" graph simply takes that set of customers and breaks them down by # of rides in that month.

Bookings can grow more slowly than customers if customers are spending less on average. This is in fact the case - in July 2012, customers were spending ~$85 a month on Uber. This has dropped steadily over the last three years to ~$70 a month. This makes sense given that Uber has lowered its average price over the years, with the introduction of UberX and UberPool.
