Holder, a surprise choice to lead the West Indies to the World Cup, appeared to be involved in an on-field argument with former captain Darren Sammy during their must-win final Pool B match against the United Arab Emirates in Napier.
The West Indies' eventual six-wicket victory all but propelled them into the knock-out phase, with only an unlikely tie in the final match between Pakistan and Ireland in Adelaide able to derail them.
Sammy was brought on to try to break the partnership with the score at 108-6 after 30 overs and was not happy when taken out of the attack after just one over that yielded four runs.
Sammy and Holder appeared have strong words which Holder later played down as "a little banter on the field" saying they wanted to have some fun but "unfortunately it probably didn't look that way."

Sammy later posted a picture on Instagram of him enjoying a beer with Holder in the locker room although his conciliatory smile was in stark contrast to his captain's stony-faced expression.
The West Indies World Cup campaign, which started with a shock loss to Ireland, has been dogged with suggestions of unhappiness in the camp with the 23-year-old Holder struggling to get the respect of the senior players.
But Holder rejected talk of problems and said the two-time champions were looking forward to a likely quarter-final against unbeaten New Zealand in Wellington on March 21.
The UAE, anchored by 60 from Aziz and 56 from Javed, made 175 which the West Indies took only 30.3 overs to haul in with Johnson Charles, playing his first game, hitting 55 off 40 deliveries.
Charles was called into the West Indies side after Darren Bravo was injured early in the tournament, and thrust into the starting line up against UAE at the last minute when big-hitting opener Chris Gayle pulled out with a recurrence of a back injury.
