The analysis is written poorly for the UU metagame and "terse", as X-Act put it.

Meganium is a surprisingly good supporting member in the UU environment. Energy Ball provides more reliable STAB than Grass Knot because the Bulky Waters (among other targets) are generally smaller and lighter in UU, mainly things like Quagsire and Gastrodon. Aromatherapy is always good to have, especially on a nice bulky Pokemon like Meganium, since it means he won't be having troubles with Toxic. Light Screen and Reflect can basically go either way, depending on whether your team seems more vulnerable to physical or special attacks. In normal play, Synthesis wouldn't be a real option for healing, but the lack of Sandstreamers and the increased prevalence of Sun makes it a completely viable UU option. This is a physically defensive Meganium and, while Special Defense is an option since Meganium's defensive stats are the same, Hypno and Grumpig are generally better on the special side.
[OTHER OPTIONS]
Counter is always an interesting choice, but Meganium has a hard time fitting it into his moveset, oddly. Grasswhistle can provide additional support and give Meganium an extra turn of Leech Seed or a chance to use Synthesis. Giga Drain with Big Root is an option with Leech Seed, but Meganium isn't fast enough to make it work as well as sticking with Energy Ball and Leftovers. You can use Hidden Power Fire if you want to get some additional type coverage. Earthquake is a strong move but splitting Meganium's offense isn't generally the best.
[EVS]
High HP and Defense are the order of the day. Investing in Special Defense is probably not a good idea since Meganium can already use Light Screen to boost its special defense. Additionally, Hypno and Grumpig are the kind of dominant special walls (a la Blissey) that just knock out the potential for anything else to fill the role in the same way. You can take a few slices off of Defense if you want some Speed to go before something specific.
[OPINION]
Meganium is a good team supporter in UU. His offenses are reasonable, though his offensive movepool is limited, and his defenses are quite nice. Aromatherapy is a good move to have on any team, especially one that fears status, and Meganium is no slouch at using it. His high defense is even more dangerous on Sun teams, where Synthesis generates full healing. Meganium can be a good team player in UU if used properly.
[COUNTERS]
Things that resist Grass and things with high Special Defense have no problems with Meganium. A strong Ice type like Glaceon or Froslass should be able to do some heavy damage, though Glaceon might have problems in Sun since Meganium is faster and can know Synthesis. The aforementioned Hypno and Grumpig can shut down Meganium without Earthquake.
