No. Where did you read that ?

When all else fails, read the instructions:

Ref:
http://gdcm.sourceforge.net/html/vtkGDCMImageReader_8h-source.html

00021 // .SECTION Implementation note: when reading a series of 2D
slices, user is
00022 // expected to provide an ordered list of filenames. No sorting
will be applied afterward.

See gdcm::IPPSorter for a common sorting scheme.
