[Clang][Sema] Dubious temporary expression constructing `CXXThisScopeRAII`

In

llvm-project/clang/lib/Sema/SemaTemplate.cpp

	CXXThisScopeRAII(*this, RD, ThisQuals, RD != nullptr);
	MultiLevelTemplateArgumentList MLTAL = getTemplateInstantiationArgs(

The CXXThisScopeRAII temporary is destroyed at the end of the expression. Is it meant to be a variable definition?
