[Grand Theft Auto V] How am I able to call in Merryweather to help me fight Merryweather over a Titan? Isn't that counterproductive for their business?

So here I am undertaking a mission for Lester to steal a Titan from Merryweather at LSX. I get pinned down, figure I need air support and call Merryweather to see if they'll do anything. Whadd'ya know, they arrive and start shooting the crap out of their own guys. Like I know this way they're being paid to both protect the Titan *and* help steal it, but how does their business work if they're constantly open to betraying themselves? How much are their mercenaries being paid to risk some of their allies turning on them because some fixer pays for backup against Merryweather? 

Does Merryweather have some extreme in-fighting problem? Are the terms of employment rather loose and competitive? How does this work?

Merryweather is a US-based multinational conglomerate defense contractor. The Merryweather that contracts out to you is a completely different division from the Merryweather that contracts out to defending Titans.

Besides, they have a pretty robust insurance policy.
