Always, recompresion already compresed material will give degradation of 
the quality.
All compresion except lossless provides some image distortion and as 
first compresion could give it innoticeable then each next recompresion 
follows with cumulative degradation.

As side note of this tea.mp4 material. Coders who did it was either mad 
or stupid or both - 1500kbps for AVC video at 320x240 resolution. With 
that bitrate it could be crisp & clear 640x480 or even 800x600.
