The German is well versed in late, late drama having been at the Brentford helm when Doncaster won the League One title last year.
They did so with a goal which came just seconds after Bees striker Marcello Trotta had missed a penalty with only the width of the crossbar denying them the title.
Brentford would later lose to Yeovil in the play-offs and memories of their desperate disappointment then were likely dragged up for Rosler here in a contest which saw five goals scored inside the final 12 minutes.
After Nick Powell's second-half opener, the madness began when Ishamel Miller struck a quick brace to turn the match on its head.
Yet, amazingly, with two minutes to go Wigan were winning thanks to James McArthur's equaliser and Byron Webster's own goal.
However, in the fourth minute of stoppage time, Luke Ayling bundled home a last-gasp leveller from a corner in the final act of a riveting game.
"I have never seen more drama, no, that's the way it is," said Rosler.
Had Wigan held out for a few seconds more, they would have recorded a ninth straight win in all competitions - which would have been a new record for them since they entered the Football League in 1978.
Rosler added: "We got a gift by being 3-2 up and we gave it our all. Normally we defend very well from corners and set pieces and we didn't do that.
"I knew that at one point the run would end, and when that ends with a draw, I take that."
Given Wigan's continued quest to successfully defend the FA Cup and their earlier sojourns in the Europa League, Rosler has inherited a fixture list crammed with matches.
And, with James Perch the latest injury casualty, he admits his squad's fatigue showed in the final 10 minutes.
"I felt the last 10 minutes we were down on our knees," said Rosler, who has added West Ham midfielder Jack Collison to his depleted midfield on loan for the rest of the season.
"The amount of games has shown today. Collectively we couldn't turn them as much as I wanted to get another goal. Overall I take it as it is and we move on."
The Glovers greeted each of Miller's late goals in jubilant fashion and that hysterical mood was only enhanced through Ayling's strike, which came when goalkeeper Marek Stech caused problems from the corner.
"I'm just proud of the boys, the fact they gave everything the whole game," said Yeovil manager Gary Johnson.
"We quietened a big crowd, we were frustrating them with our play but we were still creating opportunities and I certainly felt we deserved to get something out of the game.
"A draw is a fantastic result for us given the results recently that Wigan have had at home and their status in the Football League - they're a Premier League club with Premier League players.
"Little old Yeovil - we came here and took a point."
They did so through Ayling's goal, although their goalkeeper Stech was keen to emphasis the part he had played in the opposing box too.
"In the hotel before the game we said we were going to review everybody's individual runs from set plays because we haven't been happy with that," Johnson revealed.
"At the end of the game Marek came in and said 'gaffer, wait until you see the video, the good run I made in the box to create the chance for our goal'."
