</span><span style="color:#323232;">following:
</span><span style="color:#323232;"> (I) Thompson TA510D.
</span><span style="color:#323232;"> (II) Thompson TA5.
</span><span style="color:#323232;"> (xiv) All UZI types, including Micro-UZI.

It seems fairly obvious they are referring to the Uzi submachine gun en.wikipedia.org/wiki/Uzi and semiautomatic (con)versions of it.
I do agree this is not worded well. But it is also trivial to get confirmed and either keep a printed out official document in your gun safe or register your pistol anyway.
Which is how most laws like this work. Dealing with export control and similar laws is also a giant headache where you sometimes have an over specified or vague clause that just means you send an email/write a letter and keep the response on file.
