Most "series jazz" wiring diagrams you'll find online do NOT allow independent volume control in series mode. For those configurations, there is typically a single "global" volume control which applies to both pickups at the same time.
But you can
wire in series to retain independent volume control of each pickup. The trick is to think of each pickup as a "module" taking the output from the previous module as input (or ground in the case of the first pickup), and blending in a variable amount of the pickup using the pot. Each pot gets wired so that one end is connected to the previous stage as well as the negative terminal of the pickup. The opposite pot lug is wired only to the positive terminal of the pickup. The wiper is then wired to the next stage.
In answer to your question, if you wire in series this way, then the answer is Yes: soloing a particular pickup yields the same output signal as parallel wiring. (Actually, in "full solo" mode, the series option works slightly better for solo'd pickups because there is less "leakage" of signal to ground from the pickup -- half as much, in fact, for a 2-pickup instrument). The limitations are in the "blending", because rolling off any of the "downstream" stages (i.e., the bridge pup) will reduce total output volume until the pup is removed completely. So volume control is a bit tricky and non-linear, IIRC.
I think the reason this wiring isn't more popular is that it's more complex to switch back-and-forth with parallel wiring using a single DPST switch. By contrast, you CAN switch back-and-forth between parallel and "global volume" series wiring, and lots of diagrams are available to do that.
Most people are unwilling to wire in series full-time.
