You realize that suit was from before the two companies merged.

So? Filing a suit does not some how lock it into going forward. Plaintiff can stop it at any time. Motorola's suits are still going on because that is what Google wants.

The suit was filed after google struck the deal to buy Motorola, but not officially finalized.

Google announced Motorola Mobility acquisition in 2011. The suit was filed in 2012.

I believe they were still seeking regulatory approval of the acquisition when the lawsuit was filed. Either way, Apple sued Motorola first in 2011.

Any quotes on that?

Apparently you didn't get the timeline correctly. Motorola sued Apple over some FRAND SEP back in 2010. The judgement came down in 2011 in favor of Motorola. http://www.engadget.com/2010/10/06/motorola-suing-apple-for-...

In addition to that, you're quoting Don Reisinger?

Either way, the quarrels between Apple and Motorola started far before Google bought them.

I don't even know who Don Reisinger is. I googled it and linked the first result.
