The wiring/switch positions may be rearranged to suit the player's taste.
Notice that the Neck is shunted only when the Bridge is active by itself. That's because the switch (a Fender 4-way) has only two poles, hence one of the pickups must have a hot lead wired at all times to the volume control - it can't be switched like you'd find in an ordinary scheme. If we could get 3- or 4-pole 4-way switches, then the issue would go away, to be sure. But such is not meant to be, thus..........

I've struggled with this shorted pickup problem as well. May I quote you Sumgai? "The wiring/switch positions may be rearranged to suit the player's taste." I'd like to suggest that if one was to swap the pickups around on the switch (watch the polarities!) then the bridge pickup would be shunted instead and then only when the neck pickup was selected in isolation. Now, how many of us would resent a little "tone sucking" on the neck pup on a tele compared with loss of top end on the bridge pup? The vanilla Tele neck pickup with its tin hat was never exactly a stellar performer at the best of times! All that remains to be done is to reverse the orientation of the tele 4 way switch and now you have full treble on the bridge pup and (almost) the same switch positions as before. It crosses my mind that a simple push / pull pot mounted switch would avoid this question altogether and would be more intuitive in normal use. Incidentally, Joe Barden advised me not to bother with a 4-way when I wired my JBs and I believe that he was correct. (One unused Fender 4-way in the parts drawer!)
