I had a quick look at your examples on the openstreetmap site, and the OSRM 
router there does the same thing as OsmAnd, e.g. here 
<https://www.openstreetmap.org/directions?engine=fossgis_osrm_car&route=52.83930%2C6.41060%3B52.98870%2C5.55310#map=16/52.8061/6.0966>
.

In both examples, both the motorway and the exiting motorway_link are 
tagged:

maxspeed=100 

maxspeed:conditional=130 @ (19:00-06:00)


however the motorway_link to rejoin is simply tagged:

maxspeed=130


Could this theoretical increase in maxspeed be the reason that the 
motorway_link's are being chosen, even though in reality it will be slower?

I can't speak for the developers, but I get the feeling that it can be more 
difficult than you'd think to incorporate simple rules to avoid such 
behaviour, or maybe there could be unintended side-effects. Let's see if 
anyone who knows better has anything to say!
