Siemens datasheet is wrong, the pins they show are backwards. Pinout as shown by Motorola, Philips etc is very common in European transistors.

Why am I not surprised? I really didn't like dealing with Siemens because we only had problems with them when it came to any kind of documents
(datasheets, performance reports, certificates & approvals, purchase orders, software, firmware revision or whatever).
Siemens has horrible documentation in general and no understanding of document control.
Last time I used their products I found that they were sneaking in changes without changing document number, name or date.
The document increased in size by dozens of pages, important info was changed while they kept the file name, revision, date etc. all the same.
Imagine having to prove something when Siemens will simply make inconvenient data disappear.
Someone would have to force me to use them again.
