    Actually the question was very specific for those who know Global Forest Change. The answer arrived promptly and clear.

Looking at their site, they clearly state that:

Circa year 2000 Landsat 7 cloud-free image composite (first)

Reference multispectral imagery from the first available year, typically 2000. If no cloud-free observations were available for year 2000, imagery was taken from the closest year with cloud-free data, within the range 1999–2012.

Circa year 2014 Landsat cloud-free image composite (last)

Reference multispectral imagery from the last available year, typically 2014. If no cloud-free observations were available for year 2014, imagery was taken from the closest year with cloud-free data, within the range 2010–2012.
