That is plainly untrue. "ß" developed in a two-wise way: as a ligation 
of long s and round s, and as a ligation of long s and z. German adopted 
unified spelling rules only in 1901. Before that, both in the middle 
ages and in the humanist period, German spelling differed much. For 
example, "Thor" and "Tor" were equal variants of spelling the word 
meaning "gate".
Short S was denoted by different writers differently (as ſs or ſz, which 
looked like ſʒ). The graphical shape of the ß ligature developed 
independently in these two ways.
This dichotomy still shows itself in a small minority practice of 
uppercasing ß as "SZ" rather than "SS". Incidentally, this practice is 
understandable for most German readers (though not actively practiced), 
i.e. "GROSZMAUL" or "MASZGEBLICH" is understandable as the uppercasing 
of Großmaul or maßgeblich.
One interesting issue is that in the 1996 spelling reform the status of 
ß as a single letter has been finally confirmed. In the previous 
spelling, the general rule was that short vowels are denoted by 
following them by doubled consonant letters while long vowels are 
followed by single consonant letters. So writing "met" always indicates 
a long "e:" while "mett" indicates a short "e".
In case of "s"/"ß", it was confusing. Following a vowel with a single 
"s" always denoted a long vowel, following a vowel with a doubled "ss" 
indicated a short vowel, but following a vowel with "ß" did not give 
clue whether the vowel was short or long. So "Ruß" was actually 
pronounced "ru:s" as if the "ß" stood for a single consonant letter, but 
"Nuß" was pronounced "nus" as if the "ß" stood for a doubled consonant 
letter.
The 1996 spelling removed this uncertainty by changing the spelling of 
all "ß" into "ss" when the preceding vowel was to be pronounced short. 
Today’s spelling of "Nuss" or "dass" underlines that the vowels are to 
be pronounced short.
The uppercasing of "ß" as "SS" but also as "SZ" defeats this clear rule. 
If I uppercase the word "Rußpartikel" into "RUSSPARTIKEL", suddenly the 
natural way of pronouncing the "U" changes from short to long, so the 
reader is confused. The confusion is even bigger now, after the reform, 
because the special "undefined" treatment of "ß" no longer exists, so 
readers are used to "ß" being always treated as a single consonant 
letter, not as a ligature of a doubled consonant.
As I said, even writing "SZ" does not help. To remain logical, 
consistent and reader-friendly, "ß" needs (at some point) to assume a 
single graphemic shape in the uppercase.
I believe that it should be an exciting task for type designers now to 
come up with a new form. In my opinion, this issue is definitely not one 
that is completely solved. We’re in the middle of a slow transition 
period for "ß". The 1996 reform started it and showed the direction.
