Crossing way check works only for "on demand" but not for "on upload"

[ratrun]

What steps will reproduce the problem?

Precondition: In the preferences the "Crossing way" check is selected for "On demand" and for "On upload".

1. Load some data with ways
2. Create a new way (highway=residential) intersecting existing ways without creating nodes at the crossings.
3. Try to upload such a change

What is the expected result?

At least one "Crossing way" warning gets displayed
The "Unnamed way" is detected

What happens instead?

Only the "Unnamed way" warning is detected

Please provide any additional information below. Attach a screenshot if possible.

The check works fine if one presses CTRL A for selecting of all data and if the validation is then triggered manually.
The check also does not work in case one selects all data and tries to start uploading from such a state.

See screenshot. See discussion in ​http://www.openstreetmap.org/changeset/30065747
