I think what he meant is the general comment that the more pressure you have on the pedals, the harder it is for your drivetrain to execute a shift. Selecting the right gear and sticking with it for the entire hill is one approach. The single speeders here certainly know what that feels like. Another approach that I use is that when you want to shift, pedal much harder to get some extra speed going. Then let way off on the pedal pressure long enough to execute your shift. I'm talking about something like two or three hard strokes and one light stroke to do your shift. This is more necessary on the front than in the back, but its a good policy either way.
