Same maltster makes that ale malt, stout malt, lager malt and distilling malt. All different varieties of malted barley.
BSG was giving away samples of the stout malt at GABF last year. I picked some up and used it to make a hoppy lager. I got great extraction from it and the flavor was very soft and worked well for a lager. Less grainy than many pale malts. That matches the maltster's description very well.
All that is to say when the maltster's website says the ale malt is brewed to be sweeter and amber-colored I believe it's probably accurate. I'd suspect it is similar to a maris otter rather than an American pale malt.
