No big mistery of that:

FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFFEBAAEDCE6AF48A03BBFD25E8CD0364141

Ok, do you know how we can shift the place of bolded part? To make it look like this:

EBAAEDCE6AF48A03BBFD25E8CD0364141FFFFFFFFFFFFFFFFFFFFFFFFFFFFFFF

Or even better, imagine this is target :

0x0000000000000000000000000000000000000000000000000000000001234567

Now how can we make it look like this:

FFFFFFFFFFFFFFFFFFFFFFFF1234567EBAAEDCE6AF48A03BBFD25E8CD0364141

Lol, this is simple add or sub, to change all of those.

But for the last one, why would you take a smaller target and make it astronomically bigger?

One of the reasons why it might be better to add and multiply and increase the range of the keys is that ecc works like a clock. If you do an addition or multiplication that is around the end,you would automatically get a key that reflects a low range. .
Remember that there are two pairs of keys that are the same but represented in different ranges, one starts with 02 and the other with 03 in the case of compressed pubkeys.
