I have no doubt it worked the next day. The problem with solid joints like that is when expansion and contraction takes place. I used to jump tubular track with a spot of solder. After months, or maybe even a year or two, the spot of solder would crack right in the middle from the two pieces moving relative to each other! Once I started soldering a short piece of wire between the two track joints, that never happened again.
I predict a similar fate for this fix.
