To clarify the situation and to give webmasters greater control, we'll be retiring "Googlebot-Mobile" for smartphones as a user agent starting in 3-4 weeks' time. From then on, the user-agent for smartphones will identify itself simply as "Googlebot" but will still list "mobile" elsewhere in the user-agent string.Googlebot-Mobile User Agent To Retire For Smartphones [googlewebmastercentral.blogspot.com]
Here are the new and old user-agents:

The new Googlebot for smartphones user-agent:
Mozilla/5.0 (iPhone; CPU iPhone OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)

The Googlebot-Mobile for smartphones user-agent we will be retiring soon:
Mozilla/5.0 (iPhone; CPU iPhone OS 6_0 like Mac OS X) AppleWebKit/536.26 (KHTML, like Gecko) Version/6.0 Mobile/10A5376e Safari/8536.25 (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html)
The user-agent of the regular Googlebot does not change, and the remaining two Googlebot-Mobile crawlers will continue to refer to feature phone devices in their user-agent strings; for reference, these are:

Regular Googlebot user-agent:
Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)

The two Googlebot-Mobile user-agents for feature phones:

SAMSUNG-SGH-E250/1.0 Profile/MIDP-2.0 Configuration/CLDC-1.1 UP.Browser/6.2.3.3.c.1.101 (GUI) MMP/2.0 (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html)
DoCoMo/2.0 N905i(c100;TB;W24H16) (compatible; Googlebot-Mobile/2.1; +http://www.google.com/bot.html)

I'm having trouble making sense of their reasons for doing this.

Bingo. The old and new user-agents are IDENTICAL except for the -Mobile element.
