Can I wire like this?
The original diagram is technically correct.
Some experts and electrical engineering professors insist that for the original diagram large dots (see next diagram), which incidentally correspond to wire nuts, be placed over the intersections of the lines that are not jumpovers.
For ordinary ceiling recessed lights (can lights) there is usually not enough room in the small junction boxes accompanying the lights. Separate larger junction boxes, with accessible covers and somewhat suggested by the original diagram, would be needed to contain all of the wires coming together.
The third diagram above is a method of avoiding the need for extra junction boxes. As with the previous diagrams, connect all the black wires together and, in separate bundles, connect all the white wires together.
If you cut too many corners for convience's sake then you may get shenigans.
The disadvantages of crab apple trees. In summer, the apples are too sour to pick and eat. In winter the birds come and leave dropping all over the place.
