Short description of error
Select then deselect is not same as deselect then select

Exact steps for others to reproduce the error
Based on the default startup or an attached .blend file (as simple as possible).

In Edit mode ,
Group vertex group select(orange) is a strip of 1 raw width. (faces mode)
But when All faces selected, Group > Deselect ... deselection(purple) is not same as Group : it 3 raws large, instead of 1.

Similar to T59655:

if you use vertex groups, then the vertices are taken into account (not faces).
If you "deselect the whole row of faces" then actually you are deselecting two rows of vertices, then since the neighboring faces are not fully selected anymore this dont get drawn as fully selected anymore...

Not a bug here. Note in 2.8 you can use Face Maps instead (these are for faces specifically)
