"intuitive" once you know that current changes along the electrical "degree
length" in an unloaded antenna, the same should happen in the degree length
loaded coil.

Unfortunately, both sides cannot be right but both sides
are still illustrated as fact in the ARRL Antenna Book.
There's one graphic that shows the drop in amplitude
through a loading coil and another that shows no change.
Apparently, the ARRL doesn't know what happens so they
show both possibilities as technically correct.

Also, as indicated, the pictures do say 1000 words and it also looks like
W8JI ended up agreeing with you after you pointed out the same effect at
"ON4UN's Low Band DXing", 3rd Edition, on page 9-34.

Unfortunately, it is rumored that W8JI has talked ON4UN
into changing that in the latest edition. I emailed ON4UN
about it but got no reply.
