Some months after I turned this saddle valve off I turned it back on. It leaked with increasing flow until it was completely turned on. Then it stopped. Is this ok? Is it normal? Or would I be wise to replace/repair the valve.

Saddle valves are notorious for leaking and failing in just a few years. The best repair would be to install a T at the point the saddle valve is attached. This is something most DIY folks can do with plastic or copper pipe a bit more difficult if galvinised pipe. If you stay with a saddle valve get the best quality one you can find.

Is this OK?

No, you should replace the valve as soon as you have the chance, better yet would be to install a tee and regular stop-valve, preferably one of high quality.

Is it normal?

It is fairly common for older valves to leak at the stem area until back-seated (or as you said, completely turned on).
