I don't think so.

according to 7.4.3.1

---------------------------------------------------------------------------
vps_max_sub_layers_minus1 : plus 1 specifies the maximum number of temporal
sub-layers that may be present in the CVS. The value of
vps_max_sub_layers_minus1 shall be in the range of 0 to 6, inclusive.
---------------------------------------------------------------------------

If we are read 3 bit( vps_max_sub_layers_minus1 ) with 6, plus 1 and array will
be 8 ( 0~ 7 ). so MAX_SUB_LAYER should be 8.

You can find it. ( according to HM1.2 source code )

https://hevc.hhi.fraunhofer.de/trac/hevc/browser/tags/HM-12.1/source/Lib/TLibCommon/TComSlice.h
: 403 ~ 405 line
https://hevc.hhi.fraunhofer.de/trac/hevc/browser/tags/HM-12.1/source/Lib/TLibDecoder/TDecCAVLC.cpp
: 667 line ~

it MAX_TLAYER is 8. 

I think, this way is right.
