If it's already absorbed then the value is that it keeps you in your routine, as you suggested. I always tell those I work with to give themselves "5 good seconds" from the time they pick up the ball but before they start their approach. This is their chance to focus briefly on their timing, delivery, and target.
Too many bowlers go into "auto pilot" mode and pay for it in the form of an easy spare that gets missed, or something else they regret later. Engage the mind before you engage the muscles, so to speak.
If there is no oil on the ball you can still keep the routine.

I like to call it pre-shot ball inspection, which part of wiping the ball is. There are times when the ball can pick up tacky residue from the machine. If this residue happens to be in your track, it can cause some undesired effects. Wiping the ball prior to each shot ensures you have inspected the ball and made sure the surface is clean and suitable for delivery. There are many times I wipe and there is no oil just FYI. As the previous poster said though, it is also a routine that keeps things consistant.
