Typo for presenceFlag in picture header syntax

JVET-S2001-v3 has the following text in the picture header syntax:

presenceFlag = 0
if( !pps_rpl_info_in_ph_flag ) /* This condition is intentionally not merged into the next, to avoid possible intepretation of RplsIdx[ i ] being unspecified. */

presenceFlag = 1
else if( num_ref_entries[ 1 ][ RplsIdx[ 1 ] ] > 0 )

presenceFlag = 1

if( presenceFlag! ) {

ph_mvd_l1_zero_flag u(1)
if( sps_bdof_control_present_in_ph_flag )

ph_bdof_disabled_flag u(1)

if( sps_dmvr_control_present_in_ph_flag )

ph_dmvr_disabled_flag u(1)


The line "if( presenceFlag! ) {" seems to have a typo with an exclamation mark that should not be there. It is suggested to change it to "if( presenceFlag ) {".

Maybe the name of the presenceFlag could also be changed to something more meaningful such as bipredToolControlPresentFlag.
