[temp.local]/1 says that injected-class-name sometimes can be interpreted as «a type-name equivalent to the template-name followed by the template-parameter s of the class template enclosed in <>». But template-parameter is like typename T, not T.

Prolly it should say «followed by the template argument list» (See http://eel.is/c++draft/temp.decls.general#2.sentence-2, http://eel.is/c++draft/temp.arg.general#2)?
