As the little rat in the video's sign reads, "This is True":
Here are all the "Alexandrias" founded by Alexander the Great:
1.
Alexandria (in Troas): a town near Troy, founded in the Spring of 334. It may have been founded by one of Alexander's successors.
2.
Alexandria (by the Latmus): a town in Caria, maybe founded as a garrison or military settlement in the winter of 333. Probably, it was founded by one of the successors of Alexander, who called it to the former king.
3.
Alexandria (near Issus): Probably a permanent garrison where veterans of the battle of Issus could begin a new life, together with local inhabitants. Modern Iskenderun in Turkey.
4.
Alexandria: the site was chosen in January 330; the city was founded on 7 April. This was an entirely Greek city, although there was also a native quarter and a Jewish quarter. The Jews and natives were second-class citizens (text).
5.
Alexandria (in Aria): perhaps, the Arian capital Artacoana was repopulated with natives and Macedonian veterans in September 330. It was probably meant as a permanent garrison. Alternatively, this was a completely new town. Modern Herât in Afghanistan.
6.
Alexandria (in Arachosia): the Arachosian capital Kapisa was repopulated with natives and Macedonian veterans in the winter of 330/329. It was a permanent garrison. Modern Kandahâr in Afghanistan, which still bear's Alexander's name (derived from Iskandariya, the Arabic and Persian rendering of "Alexander").
7.
Alexandria (in the Caucasus): the Gandarian capital Kapiša-kaniš was repopulated with 4,000 natives and 3,000 Greek veterans in March 329. It was a permanent garrison or a Greek city, although many settles felt that it was a punitive colony. Modern Chârikâr in Afghanistan.
8.
Alexandria Eschatê: founded in the Summer of 329 as a permanent garrison on the Jaxartes (Syrdar'ya). Settled with Macedonian and Greek veterans and native serfs. Modern Khodzent in Tajikistan.
9.
Alexandria (on the Oxus): refoundation of a Persian city, settled with Greek and Iranian veterans and native serfs. Probably modern Ai Khanum in Afghanistan. Probably founded in the Spring of 328. Modern Termez?
10.
Alexandria (in Margiana): refoundation of a Persian city in the oasis of Mary in modern Turkmenistan. Settled with Macedonian, Greek and Iranian veterans and native serfs.
11.
Alexandria (on the Hyphasis): founded in July 326 at the eastern border of Alexander's empire. Settled with veterans of unknown origin.
12.
Alexandria (on the Indus): founded in February 325 on the confluence of the Indus and the Acesines (Chena

, probably on the site of an older, Persian settlement. Settled with Thracian veterans and natives. Uch in Pakistan. It had large dockyards, which suggests that it was meant as a center commerce.
13.
Alexandria (in Carmania): if this city was founded by Alexander (and not by Seleucus), it must have been a permanent garrison founded in January 324. Perhaps modern Golâshkerd in Iran.
14.
Alexandria (in Susiana): not far from the mouth of the Tigris. Probably settled with Macedonian, Greek and Iranian veterans and natives. Later known as Spasinou Charax. In the neighborhood of Al Qurnah in Iraq.
So, fourteen "Alexandrias" altogether, then. Kind of like the American habit of naming towns and cities "Springfield". I'm glad America's conquering hero didn't share Alexander's love of his own name. Can you imagine fourteen "Washingtons"?
Enough to give a libertarian nightmares.
